@@Bhavin-Desai The OP of the comment pasted it from the video description. TH-cam doesn't show the chapters on the video screen for videos longer than 12 hours, I think. You can also find them in the pinned comment.
Your Flutter tutorials have been a game-changer for me, especially with the Amazon clone project. I've gained a solid understanding of Flutter's capabilities through your clear and detailed explanations. I believe a MATRIMONY COMPLETE FLUTTER tutorial would be incredibly valuable and highly demanded in the Flutter community. It's a challenging yet fascinating project that many developers, like myself, are eager to explore. Your approach to teaching complex topics makes learning enjoyable and accessible. I'm really looking forward to seeing your expertise applied to building a matrimony app. It would undoubtedly be a fantastic addition to your tutorial series and help many of us deepen our Flutter skills. Keep up the amazing work!
first thank you for the simple tutorial, I would recommend it to anyone completely new to programming, I have a small thing to add, regarding the Colors I notices that the instructor did not explain what the Hex representation of colors is, so basically hexadecimal is a base 16 numbers systems where we start counting from 0 and finish at F (0 ---> 15), when we talk about colors, we represent them using three main colors (there are other ways to represent colors depending on the field and the usecase), these colors are Red (R), Green (G) and Blue (B), hence: RGB, the amount of each color is expressed using a number between 0 and 255 (8 bits), when we write this number using Hex we get two characters ( from 00 to FF), so basically we read FFFFFF as FF (255) for Red, FF (255) for Green and also FF (255) for Blue, which mean mix the maximum of each color (this gives white), and the extra two characters we see at the start of the color representation is called the alpha channel, it tells us the opacity of the resulting color (from 00 for transparent to FF for 100%), at this point we have AAFFFFFF for a white color with a medium opacity, one last thing to add is the Ox prefix we keep seeing, this is just to distinguish it as Hex number, anything prefixed with 0x is considered to be in base 16 (Hex) refer to Wikipedia for more info, and google the topic to get more technical details on this en.wikipedia.org/wiki/RGBA_color_model
Best Course I have come across. I have taken paid courses from Udemy, saw bunch of other tutorials. Nothing compared to what I am seeing here. Hats-off to you buddy🔥🔥🔥🔥
"Indian teachers are truly incredible! Their expertise in technology is awe-inspiring, and they possess a unique talent for sharing knowledge without revealing any confidential information. I am deeply grateful for their kindness and generosity in educating everyone on platforms like TH-cam. Thank you for your invaluable contributions!" 😊
@@famousnetwork316even more amazing. I wonder if he’s behind the Codalingo app too? Because this video and that app have got me to finally start to understand more clearly. I come from no level of coding. I understand most of the video now
This was, hands down, the best complete and beginner friendly Dart/Flutter tutorial on TH-cam! Your teaching skills are incredible and I cannot thank you enough for taking the time to share your knowledge with us. You have helped me tremendously in learning Dart and Flutter. Thank you so very much!!
This is absolutely amazing, I just finished this beginner's course and I have learned a lot as someone who is just getting into flutter space, A big thank you man, I really appreciate it🙏🏿🙏🏿.
Your attention to detail is incredible. Coming from Python, I see a lot of TH-camrs glaze over the finer points of syntax or skip them altogether, leaving me confused. You on the other hand, cover each and every point with clarity. Well done.

Hi Rivaan. Thank you for this very detailed and thorough tutorial on Dart and Flutter. I am slowly making my way through it and I'm in awe of your very precise and meaningful explanations for even the most random questions we might have. I truly appreciate that. Side note: In order for the timestamps in your video to activate as chapters, you'll need to remove the parenthesis around the timestamps in your video description. Then, it'll automatically turn into chapter titles for us to jump to a certain topic. Thank you again for sharing your wealth of knowledge with us!
Boy, i can tell that you laptop is quite powerful to handle all the running at the same time. Like bro, you're running android, IOS, web, desktop app at same time 😵💫😵💫😵💫
I have completed my 12th hour of the course, Rivaan thank you for the shared knowledge, the class is hard to stop watching and the pace is adequate for us learners.
This is a brilliant course! I'm currently 6 hours in and I'm loving it! Thank you so much for making this available for free. You have a talent for explaining concepts!
Thank you so much for this Amazing course really didnt think i would manage to watched complete 21 hours but how you teach really amazing man thats what attracted me to this course the most.
Just at the age of 18 the amount of effort you putted into the video is awesome, great man keep doing. I have learn a lot on Flutter development from you A special thanks ❤
at 11:43:31 on screen u hav "minimumSize: const Size(double.infinty, 50)," I am getting error on Size saying - "The name 'Size' is defined in the libraries 'dart:ffi' and 'dart:ui'. Try using 'as prefix' for one of the import directives, or hiding the name from all but one of the imports" what to do? can anyone tell me :) thank you!
I completed this tutorial, then Amazon clone, then Instagram Clone then I built a Facebook Clone in 3 months. But I am looking for a job or internship😢😢
If you're able to make apps using dart and flutter.. start freelancing with it! Later that experience will also help you out to land a job in the industry!
@@RivaanRanawat I wanna buy yout Udemy course where you are creating 5 social mediua app. so requesting to you please update course with latest update so i can buy faster
hey rivaan!, i dont usually comment on videos but i really like this course, i have been half through it ,like 10 hours and i going to express my thoughts about your teaching and iam going to be honest , i really like your teaching and your explanations ... one of your biggest plus is your detailed explanations of certain topics but at the same time, it is also your biggest downside.. because you are explaining every bit of information about the thing which makes it overwhelming in a certain way ... iam saying this because as for starters like me every bit of information is crucial and i think your infos are very great yet it is little bit too much .. your infos are crisp and clear , it will be great if you also keep them short .. iam just saying because you are a excellent teacher . and thankyou for this wonderful course
This is the only course I found so far that explains Dart before diving into Flutter. Thanks man! I thought Dart was difficult but it turns out to be very similar to other languages such as Java, C# and even JavaScript. I am not sure why Flutter courses for beginners are ignoring Dart!

I noticed that the timestamps in your video description are enclosed in parentheses, which prevents TH-cam from automatically creating chapters for the video. I was wondering if it would be possible for you to remove the parentheses around the timestamps in the description? This would allow TH-cam to automatically create chapters for your video, making it easier for viewers to navigate and find specific sections. It's really hard trying to navigate back to a video. Thanks for considering my suggestion! Best regards,
Just found out while searching for admin panel in flutter. I've zero knowledge right now. I'll take a week of time and let's see how much can i progress. I'll follow your tutorials. Thank you so much for uploads 😊
Wonderful Course Just completed it. what an easy-to-understand explanation to the topics of flutter. Bro taught it not just to build apps but to get real knowledge of Flutter and Dart Programming Skills. Thank, you Sirr Love you a lot.❤❤❤❤
At 10:16:04 - might be a really small tweak, but I searched a lot as to why my end brackets were all combined where as your code snippets show them nicely separated and indented. Really neat explanation.
@@randomcsguy2065 Add a comma after each Widget’s declaration and usage. This neatly separates it into a new line and not many end brackets stacked together. That was the fix for it.
**dynamic** is way more that you explained. When you use "dynamic" you create late binding, which is bad for performance. So, you should never use "dynamic" with knows types anyway. It is used in specific cases when data structure does not have a known type in code. When you call it, it tries to resolve the object signature and errors out if it can't.
I can see that you're getting amazing suggestions or samples from VSCode when hovering over colors, border radius, borders .. etc. Which extension are you using for that?
13:51:29 i want to ask something if we set borderradius property by cliprrect then is there any need to define borderradius property through shape ? i mean we can remove whole shape functionalities from Card widget ? right ??
it isn't giving me any errors when i'm not using @override keyword with implements or abstract classes just an info in dart pad. Has dart made it optional or what?, please tell somebody 4:13:56
Suppose there are two classes: class Human { void live() { print('human living'); } } class PersonA extends Human { @override void live() { print('personA is living'); } } They can be written with or without override, that's true. But, without @override, the compiler still infers that PersonA's "live" method overrides Human's based on method name and parameters. This is called as an implicit override. With @override, you are explicitly informing the compiler that "live" is meant to be an override, improving code clarity and preventing accidental overrides. It improves code readaibility too. The linter should also give you a warning regarding this. dart.dev/tools/linter-rules/annotate_overrides
@@RivaanRanawat Thanks a lot I read the doc and as I was doing this on VS code i didn't get an info of warning then I tried on dartpad and read linted and understood. So basically it's for code clarity and to avoid overriding mistakenly. Thanks a lot sir.❣️
Hey, PLEASE HELP.... In my weather app, when I have added the loading indicator, it doesn't show the loading indicator, it rather shows a red screen with error saying "null operator used on non nullable" and then the main ui screen comes back, so the error is being shown instead of a loading indicator for 1-2 seconds, I this might be caused by the "!" operator I have used with " data! ", please help me out.
Hey Rivaan, thank you so much for replying first of all, and I worked on it and found out that I wasn't handling the Snapshot.hasData properly, it should be wrapped in a if else block, if including the whole scaffold code and else containing the loading indicator code, so this I did and it started showing loading screen.... But still thankyou Rivaan for such amazing tutorial ❤️
Tnx for the video,but you should improve your English and clarify things a little better, cause you complicate them so much, but i appreciate your effort ,tnx❤
why this give me a error - print(jsonDecode(result.body)['name']); :error is - TypeError: "lat": type 'String' is not a subtype of type 'int'Error: TypeError: "lat": type 'String' is not a subtype of type 'int'
temp = data['list']['0']['weather']['main']; I am getting this error Unhandled Exception: NoSuchMethodError: The method '[]' was called on null. Receiver: null Tried calling: []("0") while accessing the required details in weather app please help me
hi rivaan plz keep those videos for free on yt plz dont think to delete them or make them for money plz u are so genius and with those videos u are helping so many people to learn flutter
the tutorial is really good and in depth but why did you not cover the filters and the search bar in the third app you just explained the ui and not the functionality
you coded function later and variables first 2:23:00 but when i did, it gave me a error that printName function should be coded before the variable. Then I wrote the function before variable and then it worked. What was my mistake? print("Best Tutorial");

@@RivaanRanawat Maybe you added after my comment. Thank you 👍
@@Bhavin-Desai The OP of the comment pasted it from the video description. TH-cam doesn't show the chapters on the video screen for videos longer than 12 hours, I think. You can also find them in the pinned comment.
Your Flutter tutorials have been a game-changer for me, especially with the Amazon clone project. I've gained a solid understanding of Flutter's capabilities through your clear and detailed explanations.
I believe a MATRIMONY COMPLETE FLUTTER tutorial would be incredibly valuable and highly demanded in the Flutter community. It's a challenging yet fascinating project that many developers, like myself, are eager to explore. Your approach to teaching complex topics makes learning enjoyable and accessible.
I'm really looking forward to seeing your expertise applied to building a matrimony app. It would undoubtedly be a fantastic addition to your tutorial series and help many of us deepen our Flutter skills. Keep up the amazing work!
Hey mate, could you please tell me that after completing this course, one can get a job?
@@khatriiedits3606 nope this are the fundamentals
That's the most explanatory and complete dart+flutter tutorial I 've ever found, thank you!
Wow, thanks! Happy it helped
first thank you for the simple tutorial, I would recommend it to anyone completely new to programming, I have a small thing to add, regarding the Colors I notices that the instructor did not explain what the Hex representation of colors is, so basically hexadecimal is a base 16 numbers systems where we start counting from 0 and finish at F (0 ---> 15), when we talk about colors, we represent them using three main colors (there are other ways to represent colors depending on the field and the usecase), these colors are Red (R), Green (G) and Blue (B), hence: RGB, the amount of each color is expressed using a number between 0 and 255 (8 bits), when we write this number using Hex we get two characters ( from 00 to FF), so basically we read FFFFFF as FF (255) for Red, FF (255) for Green and also FF (255) for Blue, which mean mix the maximum of each color (this gives white), and the extra two characters we see at the start of the color representation is called the alpha channel, it tells us the opacity of the resulting color (from 00 for transparent to FF for 100%), at this point we have AAFFFFFF for a white color with a medium opacity, one last thing to add is the Ox prefix we keep seeing, this is just to distinguish it as Hex number, anything prefixed with 0x is considered to be in base 16 (Hex)
refer to Wikipedia for more info, and google the topic to get more technical details on this

@@famousnetwork316even more amazing. I wonder if he’s behind the Codalingo app too? Because this video and that app have got me to finally start to understand more clearly. I come from no level of coding. I understand most of the video now
This was, hands down, the best complete and beginner friendly Dart/Flutter tutorial on TH-cam! Your teaching skills are incredible and I cannot thank you enough for taking the time to share your knowledge with us. You have helped me tremendously in learning Dart and Flutter. Thank you so very much!!
Rivaan you're the best. I made many tutorials and yours is the best and more clear to understand. Thanks from Brazil. Big fan of you work!
This is absolutely amazing, I just finished this beginner's course and I have learned a lot as someone who is just getting into flutter space, A big thank you man, I really appreciate it🙏🏿🙏🏿.
Your attention to detail is incredible. Coming from Python, I see a lot of TH-camrs glaze over the finer points of syntax or skip them altogether, leaving me confused. You on the other hand, cover each and every point with clarity. Well done.
Thanks, I'm happy you found this useful! Quite a coincidence as I just launched Python tutorial on the channel haha!

Hi Rivaan. Thank you for this very detailed and thorough tutorial on Dart and Flutter. I am slowly making my way through it and I'm in awe of your very precise and meaningful explanations for even the most random questions we might have. I truly appreciate that.
Side note: In order for the timestamps in your video to activate as chapters, you'll need to remove the parenthesis around the timestamps in your video description. Then, it'll automatically turn into chapter titles for us to jump to a certain topic.

hey rivaan!, i dont usually comment on videos but i really like this course, i have been half through it ,like 10 hours and i going to express my thoughts about your teaching and iam going to be honest , i really like your teaching and your explanations ... one of your biggest plus is your detailed explanations of certain topics but at the same time, it is also your biggest downside.. because you are explaining every bit of information about the thing which makes it overwhelming in a certain way ... iam saying this because as for starters like me every bit of information is crucial and i think your infos are very great yet it is little bit too much .. your infos are crisp and clear , it will be great if you also keep them short .. iam just saying because you are a excellent teacher . and thankyou for this wonderful course
This is the only course I found so far that explains Dart before diving into Flutter. Thanks man! I thought Dart was difficult but it turns out to be very similar to other languages such as Java, C# and even JavaScript. I am not sure why Flutter courses for beginners are ignoring Dart!

Amazing Course
this chanel is hidden gem 💎
Glad you think so!
This is cool, Please be releasing the video in smaller chunks in a playlist
I noticed that the timestamps in your video description are enclosed in parentheses, which prevents TH-cam from automatically creating chapters for the video.
I was wondering if it would be possible for you to remove the parentheses around the timestamps in the description? This would allow TH-cam to automatically create chapters for your video, making it easier for viewers to navigate and find specific sections. It's really hard trying to navigate back to a video.
Thanks for considering my suggestion!

Loved your tutorial sir.Amazing.
**dynamic** is way more that you explained. When you use "dynamic" you create late binding, which is bad for performance. So, you should never use "dynamic" with knows types anyway. It is used in specific cases when data structure does not have a known type in code. When you call it, it tries to resolve the object signature and errors out if it can't.
I can see that you're getting amazing suggestions or samples from VSCode when hovering over colors, border radius, borders .. etc. Which extension are you using for that?

void main(){
String value='hello';
for(int i=0;i

They can be written with or without override, that's true.
But, without @override, the compiler still infers that PersonA's "live" method overrides Human's based on method name and parameters. This is called as an implicit override. With @override, you are explicitly informing the compiler that "live" is meant to be an override, improving code clarity and preventing accidental overrides. It improves code readaibility too.
The linter should also give you a warning regarding this.
dart.dev/tools/linter-rules/annotate_overrides
@@RivaanRanawat Thanks a lot I read the doc and as I was doing this on VS code i didn't get an info of warning then I tried on dartpad and read linted and understood.
So basically it's for code clarity and to avoid overriding mistakenly.
Thanks a lot sir.❣️
Hey, PLEASE HELP....
In my weather app, when I have added the loading indicator, it doesn't show the loading indicator, it rather shows a red screen with error saying "null operator used on non nullable" and then the main ui screen comes back, so the error is being shown instead of a loading indicator for 1-2 seconds, I this might be caused by the "!" operator I have used with " data! ", please help me out.
can you share your future builder code?
Hey Rivaan, thank you so much for replying first of all, and I worked on it and found out that I wasn't handling the Snapshot.hasData properly, it should be wrapped in a if else block, if including the whole scaffold code and else containing the loading indicator code, so this I did and it started showing loading screen....
But still thankyou Rivaan for such amazing tutorial ❤️
