FilePicker.platform.pickFiles() hangs indefinitely when no compatible app is available

[ale24dev]

Description:

When calling FilePicker.platform.pickFiles() on devices that don't have any compatible file manager applications installed, the method hangs indefinitely without returning a result or throwing an exception. This creates a poor user experience as the app becomes unresponsive and users have no feedback about what's happening.

Expected Behavior

The method should either:

• Throw an exception that can be caught and handled appropriately
• Provide a way to check if file picking is available before attempting to open the picker

Actual Behavior

• FilePicker.platform.pickFiles() never completes execution
• The Future never resolves (neither success nor error)
• No exception is thrown
• Debugger never reaches the if (result != null) clause

Steps to Reproduce

• Use a device/emulator without any file manager apps installed
• Remove or disable system file managers (DocumentsUI, Files by Google, etc.)
• Call FilePicker.platform.pickFiles()
• Observe that the method never returns

Same issue here. And possible related to this Pull Request: #1736 ?

When it is on iOS mobile devices. (I don't have Android device on hand).

I wonder it should be at least a default file manage shows.

    final result = await FilePicker.platform.pickFiles(
      allowMultiple: true,
      onFileLoading: _onFileLoading,
    );

  void _onFileLoading(FilePickerStatus status) {
    setState(() {
      _uiState =
          status == FilePickerStatus.picking ? _UiState.loading : _UiState.idle;
    });
  }

I am using

• file_picker 8.1.4
• Flutter 3.24.5
• Safari on iPhone with iOS 18.6
