Flutter in Practice - E07: Automatic JSON Serialization

Flutter in Practice is a free programming course that teaches how to write a mobile application using Flutter framework and Dart programming language. Instead of teaching concepts and ideas in both Flutter and Dart, this course showcases a process of building an actual, mobile application.
In this tutorial, we will create an email client that exclusively supports JMAP protocol.

hi. the [ part 'Message.g.dart'; ] needs to be [ part 'message.g.dart'; ] in lowercase naming convention. I found about that by trial and error method. Thx

To anyone wondering how to create toJson at the same time after using json_annotation, add getter to your class like this:
Map<String, String> get toJson => _$ClassNameToJson(this);
where _$ClassNameToJson is function generated in class_name.g.dart file.

At 0:31 line 19 you show the return value of the loadMessageList function declaration to be a Future. Shouldn't this be void? loadMessageList doesn't return anything. It just calls setState() and sets messages = _messages. Not picking, just trying to understand. Great videos!

[mcwongatron]

I needed to migrate the project to AndroidX for the build_runner step to work

[moaazElneshawy]

when i try to add the command,
this is what I get >> bash: flutter: command not found

[mrpakravian]

may be with a nested json
with double dimensional array
like data grouped by date
and dispaying with sticky headers

also to map function and then to list is been very confusing
if possible pl adress those issues
i hope i am not asking too much

cant create the file '...g.dart. the vscode doesnt recognize the flutter name in the cmdlet

[mrpakravian]

thanks vry much again
plz put some more light on it
if you could

[LuminousAsianBeauties]

for someone who still can not generate "message.g.dart".
the file name need to be the same.
For example:
the file of Message model class is message_model.dart
and you wrote: part 'message.g.dart'; .It will NOT WORK.
you need to change to : part 'message_model.g.dart';
and then run: flutter pub run build_runner build
and Voila, working :o)
So depend on the name of model class dart file name. Be careful :o)
