User reported: 'input field still need to click twice' on iPhone.
The 020be77 Listener + requestFocus() approach was insufficient.
Root cause analysis:
* Flutter's EditableText opens the platform TextInput method
channel (which is what slides the iOS soft keyboard up) only
after a TapGestureRecognizer wins the gesture arena.
* Our outer Listener calls node.requestFocus() pre-arena. That
flags the FocusNode as focused in Flutter's focus tree, but
does NOT open the TextInput channel \u2014 so iOS keeps the OS
keyboard hidden until EditableText's own tap recognizer wins
on a second tap.
* requestFocus on its own is therefore a no-op for the user
visually: the cursor + caret appear briefly but the keyboard
stays down.
Fix: in the Listener.onPointerDown handler, additionally invoke
'TextInput.show' on SystemChannels.textInput. This is the same
private platform RPC EditableText calls internally on attach;
forcing it ourselves slides the keyboard up regardless of arena
state.
Belt-and-braces with the existing requestFocus() guarantees
keyboard-on-first-tap on iPhone / iPad and is harmless on:
* Android (the platform ignores the redundant show call when
the keyboard is already up),
* Linux / Windows / macOS desktop (no soft keyboard exists; the
method channel handler returns success without doing
anything).
No new imports needed \u2014 SystemChannels is already in
package:flutter/services.dart (imported for FilteringTextInputFormatter).
