How to show Linear Progress Indicator in Flutter

Progress Indicators have their own importance in mobile app UI. A progress indicator lets the user know that something is happening behind the screen. In this blog post, I will explain how to add a horizontal or linear progress indicator in Flutter.

The LinearProgressIndicator widget is used to display a horizontal progress indicator with material design in Flutter. See the code snippet given below.

LinearProgressIndicator(
          backgroundColor: Colors.red,
          color: Colors.yellow,
        )

You will get the following output of linear progress indicator with yellow color and red color background.

Following is the complete code.

import 'package:flutter/material.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: const MyHomePage(),
    );
  }
}

class MyHomePage extends StatelessWidget {
  const MyHomePage({super.key});

  @override
  Widget build(BuildContext context) {
    return Scaffold(
        appBar: AppBar(
          title: const Text('Flutter Linear Progress Indicator'),
        ),
        body: const Center(
            child: LinearProgressIndicator(
          backgroundColor: Colors.red,
          color: Colors.yellow,
        )));
  }
}

Similarly, you can also add a circular progress indicator using CircularProgressIndicator class.
