Please help: I tried to recreate it but in the "question.dart" file I keep getting the error " The parameter 'selectedOption' can't have a value of 'null' because of its type, but the implicit default value is 'null'." for the " this.selectedOption" area. I tried to "require" it like " require this.selectedOption" which takes away the error but it causes havoc in the data questions page. I tried looking for the solution everywhere but could not find it. I am a beginner coder. Any help would be appreciated. Thank you.
Hello, thank you very much for sharing, could you explain to me where I can find the final code? From what I see what is on github is the initial code.
Bravo to you. Very informative contents. Can you make a video about (firebase CRUD operation, or registration operation, handling busy state with Riverpod, handling login form data, validations, and error states using Riverpod and Freeze, establishing Model-View-ViewModel approach in order to separate ui and business logic, something like that. I am currently using Stacked Package but I would like switch to Riverpod, Freeze side, keeping use of MVVM aproach.
nice. please create a tutorial on flutter dot graph. that graph that displays dots with values after performing mathematical calculations. never seen one tutorial on youtube
Thank you so much for your tutorials, you are a great teacher, Johannes Milke! I get an error "ScrollController not attached to any scroll views. Failed assertion: line 107 pos 12: '_positions.isNotEmpty'", although I followed the tutorial. I hope one day I will be able to learn how to fix it
Thank You VladarSkopin! Follow this link: stackoverflow.com/questions/60967898/how-to-solve-failed-assertion-line-110-pos-12-positions-isnotempty-scrollc I hope you will get your answer 🙂
People see that your illustration is the best, but i say that illustrating a whole tutorial using Command + Z is the best thing! HOW do you do it without a mistake when deleting each line in the right backward order before recording? xDD
This might help you :)
