@override Future<void> pickFiles(BuildContext context, FilePickerAction action, ScopeManager? scopeManager)

Opens the platform file picker and stores selected files in the action scope.

Implementation

@override
Future<void> pickFiles(BuildContext context, FilePickerAction action,
    ScopeManager? scopeManager) async {
  final type = pickType(action);
  FilePicker.platform
      .pickFiles(
    type: type,
    allowedExtensions:
        type == FileType.custom ? action.allowedExtensions : null,
    allowMultiple: action.allowMultiple ?? false,
  )
      .then((result) {
    if (result == null || result.files.isEmpty) {
      if (action.onError != null) {
        ScreenController().executeAction(context, action.onError!);
      }
      return;
    }

    final selectedFiles = result.files
        .map((file) => FileExtension.fromPlatformFile(file))
        .toList();
    final fileData = FileData(files: selectedFiles);
    if (scopeManager == null) return;
    scopeManager.dataContext.addDataContextById(action.id, fileData);
    scopeManager
        .dispatch(ModelChangeEvent(SimpleBindingSource(action.id), fileData));
    if (action.onComplete != null) {
      ScreenController().executeAction(context, action.onComplete!);
    }
  });
}
