What’s GestureDetector?

GestureDetector class is a widget that detects gestures and attempts to recognize gestures that correspond to its non-null callbacks.

GestureDetector explained for Android Developers

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. By default, a GestureDetector with an invisible child ignores touches; this behavior can be controlled with the behavior property.

Example Code

Here is an example of how to use GestureDetector:

GestureDetector(
  onTap: () {
    // Handle tap
  },
  child: Container(
    color: Colors.yellow,
    child: Center(child: Text('Tap me!')),
  ),
);

GestureDetector Remarks

The GestureDetector widget is essential for handling user interactions in Flutter applications, allowing developers to create responsive and interactive UIs.
