FilePicker.platform.pickFiles() hangs indefinitely when no compatible app is available #1850
Description
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
