GestureDetector

A widget that detects gestures.

Attempts to recognize gestures that correspond to its non-null callbacks.

If this widget has a child, it defers to that child for its sizing behavior. If it does not have a child, it grows to fit the parent instead.

GestureDetector(
  onTap: () {
    const snackBar = SnackBar(content: Text('Tap'));

    ScaffoldMessenger.of(context).showSnackBar(snackBar);
  },
  // The custom button
  child: Container(
    padding: const EdgeInsets.all(12.0),
    decoration: BoxDecoration(
      color: Colors.lightBlue,
      borderRadius: BorderRadius.circular(8.0),
    ),
    child: const Text('My Button'),
  ),
)
