Keeping it local: Managing a Flutter app's data
ฝัง

- Data locality can make or break your app's performance. Sometimes storing data in the cloud isn't feasible. Or sometimes data needs to be kept locally for caching or until the user's on a reliable internet connection. Here, we'll explore strategies and methods for storing data locally. We start from simple key/value stores and work our way up into more complex persistence mechanisms.

Thanks for the video. It explains some of the basic concepts on how to manage data locally taking advantage of disk-read speed and I definitely picked up on the concepts. Please a future video on how to sync local data to the cloud once internet connection is established will be greatly appreciated.
Super important topic! It's something that we've spent a lot of time striking the right balance (what to cache, what is absolutely critical to have fresh from the server.) Thanks for making this video!
A great video for beginners on how and why store data locally!
Thank you
Very informative, easy to follow, thanks a lot!
Excellent explanations!! Thank you for sharing your knowledge. 👏🏽👏🏽👏🏽
Thanks, man! This was really helpful and much needed 💯💖
This video is perfect timing for me. Performance using local storage is crucial. You explained the concepts Really we'll. I would imagine this is important for flutter on the web, with different storage options to engineer than mobile. All good 👌 cheers.
Omg, why did I never view this awesome video ✨ thank you so much Andrew Fitz 💪🏼 I understood every single word 👌🏼
Good video. One of the better Flutter videos I have seen.
It's not only informative. I love listening to Andrew. Such a joy and never booring
Thanks Andrew. Very nice presentation
good content and happily able to digest, thanks for making this
Brilliantly presented thanks. Can you do a follow up showing best practice for refreshing locally stored / cached data once internet is available again?
Awesome lecture thank you. Moar of these pls!
Really good explanation Thank you
Great video. Thanks!
great explanation!
Thank you, God bless you
AWESOME vid!
Brilliant !!!
Midnight course 😴, need some coffee here
Same here....midnight studying. Ain't nothing better.
do you have series of similar videos - great way to learn flutter
Brilliant lecture. Thank you so much
sweet! App feels much snappier.
Thanks a lot
Great explanation. What extension in vscode to flutter?
What if I wanted to save files locally in a structured database until I eventually got connected to the internet, how could I do that sync thing?
Nice video
I think it will be useful to have video about console commands
Yeah, especially how you can enter the app's data folder in AndroidStudio
Lovely
It would have been useful if you would have explained a bit more on how to delete those cached images automatically after we hit a certain memory level.
There is a cache manager property, I think that's what you need
@@kirill4531 yeah I know about that, but I wanted to know how to use that efficiently or perfectly according to different needs.
Flutter forever
How did you get the waiting times to display in the terminal? Looks useful
.addListener to this question :)
I'm still waiting a simple and out of the box solution for state management in Flutter, like React Hooks and Context API. There are a bunch of cool built-in widgets already, invest more time creating some cool abstraction for us.
Hi Andrew, nice explanation, thx, please note,that CachedNetworkImage is working fine, but after some time (say a couple of weeks) you get cache errors, images are somehow not readable anymore ... this will eventually crash the app 😭 only solution I found, is clearing the Cache from time to time.
Best wishes jt
Could you list the common uses of shared preferences? I understand it is not for critical data, but that's all I know right now.
Go to officiall Flutter docs site
can you please make a course about comparing database packages? like sqflite, moor, hive, objectDB, sembast?
or can anyone introduce any?
Anybody knows how he connected to the ios device through the command line? I wish he said so in the video. It would have helped. Nice video. Thanks
Loved the video, but light theme in vs code should be illegal
Hi .. I'm waiting for next video .. how you'll manage api provider data and local data to keep them in sync.
Better go for firebase🙂
Hi guys, I need some help: We are working in a streaming app for android tv (in flutter) and after a few days the screen goes to black, exist some option to refresh automaticly (once a day for example) the caché to fix that problem?
Which extension do you use for the TODO comment at 25:20?
Use TODO Tree at VS Code
I see you can access app's files in the terminal, why I can't access this folder in AndroidStudio in File Explorer tab?
vs code maybe
🕺🏾
What is the best way to save API keys
Save it in .env file
Those that are present in Android Manifest file you can't do anything about it, they will be visible any way.
Those that you can use in the code try to encode them
are there app with flutter?
I do not see anywhere
flutter -> fake ?
Why you never hide the terminal....
hi ,, i am using flutter SDK 1.20 a bit old not yet upgraded to 2.10+ can you suggest me how to create external Storage Folders in Android?? This is Quite important to me as Android 11 is not allowing me to create external Storage. Kindly reply me or ping me directly...
"Without data, the app would be uninformed." Was that an intentional pun?
Thank you for this video, but images still loading slow even if we save it and call locally
@teriitube I was using Flutter-web, and I had images inside the assets folder. The problem was with the image size(over 1Mb). I published it, and the images were loading slower than I expect. Whatever I should use flashy for those images. (I will use it for the next project :D)
Don't look at this and complain, this is for my reference:
-------------------------------------------
9:34 Shared Preference
23:43 Caching images to disk
31:52 SQFLite
But you said *state* ment
I don't want to be negative but frankly I don't see the point of this 45 minutes video to say that "yeah you can store data locally" ... duh.
Now I would have loved a video about how to sync your local unconnected data to the cloud once you're connected.
True
true, but for beginners, this video does a great job at explaining why we need to store data locally, what are benefits and different ways to store it.
I’ve encountered problem after problem downloading flutter five days and four times deleting everything and redownloading and its still not working ready to delete it all permanently. Absolute joke this. They want people to get into tech, but make the process of it that problematic it puts us off. And on top of that flutter doesn’t even have any kind of customer service and i joined reddit just to try and get help and still not further forward. Cant even speak with anyone for help with android studio either tech companies with no tech support laughable.
Hm, I felt like the Flutter setup was one of the easiest that I had to do
Why is statement management a nightmare in flutter
when is it a nightmare? there are so many easy solutions like provider, stream.
It's not, it's pretty good actually
