• TextFormField: Extension of TextField, commonly used in forms (Form). Provides additional capabilities for managing state and validation.

Widgets for text selection:

• TextSelectionHandleType: Defines the type of text selection handle (start, end, all).
• TextSelectionOverlay: Widget that displays a contextual menu with actions when text is selected (copy, cut, paste).

  decoration: InputDecoration(
    labelText: 'Username',
  ),
  onChanged: (text) {
    // Handle text change
  },
);

  child: TextFormField(
    decoration: InputDecoration(
      labelText: 'Email',
    ),
    validator: (value) {
      if (value == null || value.isEmpty) {
        return 'Please enter email';
      }
      return null;
    },
  ),
);
