CustomFormWrapper class
A custom form wrapper widget that listens to keyboard input (Enter key) and optionally triggers a callback when Enter is pressed.
This widget:
- Wraps a Form with a FocusTraversalGroup for custom keyboard traversal policy.
- Automatically requests focus after the first frame.
- Listens to key events, especially the Enter key.
Can be useful for submitting forms using keyboard input.
