Getting started
You should ensure that you add the router as a dependency in your flutter project.
dependencies:
percent_indicator: ^4.2.5
You should then run flutter packages upgrade or update your packages in IntelliJ.
Example Project
There is a example project in the example folder. Check it out. Otherwise, keep reading to get up and running.
Usage
Need to include the import the package to the dart file where it will be used, use the below command,
import 'package:percent_indicator/percent_indicator.dart';
