const kButtonHeight = 48.0;
return Padding(padding: const EdgeInsets.all(kScreenPadding), child: const SizedBox(height: kButtonHeight));

Critical
Avoid Empty Methods
Detect methods that have an empty body. If a method is empty, ensure that a comment is present explaining why it remains unimplemented.

Critical
Avoid modifying built-in prototypes
Detect modifications to built-in prototypes. Modifying built-in objects can lead to compatibility issues and unexpected behavior. Recommend creating helper functions instead.
