Bug: Flutter Web build fails with latest file_picker – FilePicker.platform removed #1180
Description
Bug Description
Flutter Web builds fail when using appflowy_editor 6.2.0 together with recent versions of the file_picker package.
The issue occurs because appflowy_editor still uses the deprecated/removed API:
FilePicker.platform
This API no longer exists in recent file_picker versions (e.g. >=10.3.9), causing compile-time errors for Flutter Web (both dart2js and dart2wasm).
How to Reproduce
Create a Flutter Web project
Add appflowy_editor: 6.2.0
Allow file_picker to resolve to a recent version (e.g. ^10.3.6)
Run:
flutter build web
Build fails during compilation
Expected Behavior
appflowy_editor should use the new cross-platform file_picker APIs:
FilePicker.pickFiles()
FilePicker.saveFile()
FilePicker.getDirectoryPath()
so it remains compatible with current and future file_picker releases, especially on Flutter Web.
Operating System
Environment Flutter: 3.38.1 (stable) Dart: 3.10.0 Platform: Web (dart2js / dart2wasm) appflowy_editor: 6.2.0 file_picker: >= 10.3.9 (resolved transitively)
AppFlowy Editor Version(s)
appflowy_editor: ^6.1.0
Screenshots
No response
Additional Context
Error: Member not found: 'platform'.
fp.FilePicker.platform.pickFiles()
fp.FilePicker.platform.saveFile()
fp.FilePicker.platform.getDirectoryPath()
Source:
lib/src/editor/util/file_picker/file_picker_impl.dart
Suggested fix
Update appflowy_editor to remove all usages of FilePicker.platform
Use the new static APIs provided by file_picker
Optionally add an upper bound constraint for file_picker until compatibility is ensured
Additional context
This issue started appearing immediately after file_picker 10.3.9 was published, without any code changes on the app side, due to caret (^) dependency resolution.
Thanks for maintaining AppFlowy Editor 🙏
Happy to test or submit a PR if needed.
