touch_indicator

When you are recording a screencast of your app, you often want to give visual indication of where your fingers are touching the screen. Showing that on Android is easy. On iOS it's less intuitive. touch_indicator makes it easier and consistent on both platforms.

You add this widget as the main widget where you want to display user touches. Usually this will be the direct child of your MaterialApp. It will show an indicator on every touching finger and is completely customizable.

Installation

Add the plugin to your pubspec.yaml:
