GestureDetector Explained | Flutter for Web Developers

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 Web 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. GestureDetector also listens for accessibility events and maps them to the callbacks.

Example Code

Here is an example of how to use GestureDetector:

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

GestureDetector Remarks

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