I solved using a combination of padding, constraints and style padding:
``` IconButton( padding: EdgeInsets.zero, constraints: BoxConstraints(), style: ButtonStyle( padding: WidgetStateProperty.all(EdgeInsets.zero), tapTargetSize: MaterialTapTargetSize.shrinkWrap, ), onPressed: () => _onModifyDriverClicked(driver), icon: const Icon(Icons.edit_note_rounded, color: Colors.black, size: 30,)), ```

I solved using a combination of padding, constraints and style attributes:
```dart IconButton( padding: EdgeInsets.zero, constraints: BoxConstraints(), style: ButtonStyle( padding: WidgetStateProperty.all(EdgeInsets.zero), tapTargetSize: MaterialTapTargetSize.shrinkWrap, ), onPressed: () => _onModifyDriverClicked(driver), icon: const Icon(Icons.edit_note_rounded, color: Colors.black, size: 30,)) ```
