[reactive_forms_generator] not compatible with new Dart 3.9.0

[M-Ahal]

New analyzer, source_gen, fe_analyzer_shared, build versions are needed if someone wants to use Dart 3.9.0. Just migrating the dependencies breaks the whole project because no migration was done:

Migrate to the new packages is needed for the new Flutter 3.35.x which uses Dart 3.9.0

[ManuelRauber]

@vasilich6107 Could you take a look at this, please? This results in being unable to upgrade apps due to the use of source_gen v2 and other generators have started to hop on v3.

[vasilich6107]

Hi
Migration to build: 3.0 is in progress
Unfortunately there is no ETA for now

Generator works completely fine with latest flutter version
The only issue is build: 3.0 migration

Hi Migration to build: 3.0 is in progress Unfortunately there is no ETA for now

Generator works completely fine with latest flutter version The only issue is build: 3.0 migration

Ok, my personal issue is not that the generator does not work, but it prevents me from upgrading other dependencies due to build v3.

Is there anything I can help you with?

[M-Ahal]

Another generative package that I was using also recently did this migration. I tried to apply what they did, but I'm very new to this whole AST and generators meta programming in Dart. If it helps, injectable did this too, if you need some reference to it.

For me the generator does not work at all because of the 'null-aware-elements' flag. I had to make a script that switches to a Flutter SDK with Dart 3.8, run the build_runner and switch back

[alejandrogiubel]

Any update on this?

@alejandrogiubel This is my temporary workaround using puro:

#!/usr/bin/env bash

set -e

# Switch to last best SDK version
puro create rfg_temp 3.32.8 || true && puro use rfg_temp

# Run the build runner + cleanup chain
flutter pub get
dart run build_runner build -d --enable-experiment null-aware-elements && dart fix --apply && dart format .

# Change back to current
repo_root_name="$CI_PROJECT_NAME"
puro use "$repo_root_name"
flutter pub get

I've submitted a pull request to address the Dart 3.9.0 compatibility issues outlined in this issue.
@vasilich6107

#198

[vasilich6107]

Hi
Please check latest reactive_forms_annotations 8.1.0-beta0 for build 3 support

[M-Ahal]

#198

Works with these package versions

[LahaLuhem]

Hi Please check latest reactive_forms_annotations 8.1.0-beta0 for build 3 support

@vasilich6107
Won't be compatible with analyzer 8.x.x.
Used in for example, injectable_generator: ^2.9.0 (requires analyzer ^8.1.1).

I've submitted a pull request to address the Dart 3.9.0 compatibility issues outlined in this issue.

But does work with this.
