[BUG]: Import conflict: Image class defined in flutter and rive

[codeOfJannik]

Is there an existing issue for this?

• I have searched the existing issues

Version

5.6.0

Command type

build_runner (Default)

What happened?

Out of nowhere we started to get an error in the generated file that a image class is found both in package/flutter/...widgets.dart and package/rive:
The name 'Image' is defined in the libraries 'package:flutter/src/widgets/image.dart (via package:flutter/widgets.dart)' and 'package:rive/src/rive_core/shapes/image.dart (via package:rive/rive.dart)'.

Anyone else already faced that issue? Has anything changed in the package?
Or did something change in rive, e.g. they started to export the image class so it's visible?

A workaround for now is to add a hide Image to the rive import manually after the assets.gen.dart file has been generated.

Our assets folder contains png, jpg, svg and riv files.

Relevant a pubspec.yaml.

  flutter:
    sdk: flutter
  flutter_svg: ^2.0.10+1

Hello,

The error appears starting with rive version 0.13.10.

Version 0.13.9 doesn't export Image. For now, we will stay on rive 0.13.9 so we "avoid" this error.

[AlexV525]

Sounds like a rive issue which means the issue should be reported to the rive package?

[codeOfJannik]

Why? If the rive package needs to export the image class they can do that. The flutter_gen rive import statement should be adjusted to hide Image from rive

[Sevastyan]

Not hide, but flutter_gen must have been using aliases for imports in the first place. Otherwise, the issue might return.

We have a relatively long releasing procedure. If you're encountering the issue you can use the fix in the PR #548 by overriding dependencies.

Hello,

Just wanted to say thank you for the upcoming fix and the ongoing support of flutter_gen. This is what makes the Flutter community thrive, and it helps many.

its better to use import alias just like mockito generator)
