[Bug] build_runner won't detect anything - because forget to add dependency libraries

[lattice0]

Describe the bug

My generated .dart file has

part 'dart_bridge_generated.freezed.dart';

and even though flutter_rust_bridge automatically runs build_runner, it detects nothing. build_runner is on my dependencies. Also, I tried manually:

flutter pub run build_runner build

Solution: flutter pub add --dev freezed

but also make sure of the following:

flutter pub add freezed_annotation
flutter pub add --dev build_runner

[fzyzcjy]

Solution

Yes you need to do that.

Feel free to PR :) For example, when flutter_rust_bridge_codegen runs and wants to output a freezed dart class, it should check pubspec.yaml, and ensure there are freezed, freezed_annotation, build_runner there on dependencies/dev_dependencies sections.
