Is there a way in Flutter to catch the “start-moving” event in a Dismissible Widget?

Question

I am using the Dismissible widget to be able to remove certain screens/widgets from a flutter app by swiping them up.

What I need to achieve is to blur the image once the user starts swiping/dismissing them but the widget only has the "onDismissed" callback, but does not offer a way to catch the swiping event.

Any alternatives?

Answer 1

You can achieve That using the GestureDetector widget

// This is the sample
GestureDetector(onPanUpdate: (details) {
  if (details.delta.dx > 0) {
    // swiping in right direction
  }
});

You can check there are many events that you can trigger like onHorizontalDragUpdate, and many more you can check out.
