Flutter web，禁用对 Tab 按下按钮的关注

Question

我有一个文本字段，然后是一个按钮，然后是一个文本字段。
在 Tab 键按下焦点转到第一个 Textfield，在 Tab 键再次按下焦点转到按钮。当按下 Tab 键 2 次时，如何忽略按钮的焦点并将焦点放在第二个文本字段上？

这是结合了onEditingComplete的解决方案和 RawKeyboardListener .onEditingComplete用于捕捉ENTER关键同时 RawKeyboardListener用于 TAB key

class HomePage extends HookWidget {
  @override
  Widget build(BuildContext context) {
    final firstFieldFocusNode = useFocusNode();
    final secondFieldFocusNode = useFocusNode();
    return Scaffold(
      body: Container(
        padding: EdgeInsets.all(16.0),
        alignment: Alignment.center,
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: [
            RawKeyboardListener(
              focusNode: firstFieldFocusNode,
              onKey: (event) {
                if (event.logicalKey == LogicalKeyboardKey.tab) {
                  secondFieldFocusNode.requestFocus();
                }
              },
              child: TextFormField(
                decoration: InputDecoration(labelText: 'First field'),
                onEditingComplete: () {
                  print('ICI');
                  secondFieldFocusNode.requestFocus();
                },
              ),
            ),
            const SizedBox(height: 48.0),
            ElevatedButton(onPressed: () {}, child: Text('CLICK ME')),
            const SizedBox(height: 24.0),
            TextFormField(
              focusNode: secondFieldFocusNode,
              decoration: InputDecoration(labelText: 'Second field'),
            ),
          ],
        ),
      ),
    );
  }
}
