Flutter Gradient Text Examples

This concise, practical article will walk you through three complete examples of creating gradient text in Flutter. We’ll use only the built-in features of Flutter and won’t rely on any third-party libraries.

Example 1: Linear Gradient Text (with Shader)

The full code (with explanations):

// main.dart
import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
        // Remove the debug banner
        debugShowCheckedModeBanner: false,
        title: 'Kindacode.com',
        home: HomePage());
  }
}

class HomePage extends StatelessWidget {
  // Creates a Shader for this gradient to fill the given rect
  final Shader _linearGradient = const LinearGradient(
    colors: [Colors.yellow, Colors.deepPurple],
    begin: Alignment.centerLeft,
    end: Alignment.bottomRight,
  ).createShader(const Rect.fromLTWH(0.0, 0.0, 320.0, 80.0));

  HomePage({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('Kindacode.com'),
      ),
      body: Center(
        child: Text(
          'KINDACODE',
          style: TextStyle(
              fontSize: 50,
              fontStyle: FontStyle.italic,
              fontWeight: FontWeight.bold,
              foreground: Paint()..shader = _linearGradient),
        ),
      ),
    );
  }
}

Example 2: Linear Gradient Text (with ShaderMask)

Screenshot:

The code:

// main.dart
import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return const MaterialApp(
        // Remove the debug banner
        debugShowCheckedModeBanner: false,
        title: 'Kindacode.com',
        home: HomePage());
  }
}

class HomePage extends StatelessWidget {
  // Create a linear gradient
  final Gradient _gradient = const LinearGradient(
    colors: [Colors.yellow, Colors.deepPurple],
    begin: Alignment.topLeft,
    end: Alignment.bottomRight,
  );

  const HomePage({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('Kindacode.com'),
      ),
      body: Center(
        // Use ShaderMask to apply the gradient as the text color
        child: ShaderMask(
          blendMode: BlendMode.modulate,
          shaderCallback: (size) => _gradient.createShader(
            Rect.fromLTWH(0, 0, size.width, size.height),
          ),
          child: const Text(
            'ABCDEFGH',
            style: TextStyle(
              color: Colors.white,
              fontWeight: FontWeight.bold,
              fontSize: 60,
            ),
          ),
        ),
      ),
    );
  }
}

Example 3: Radial Gradient Text (with ShaderMask)

Screenshot:

The code:

// main.dart
import 'package:flutter/material.dart';

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

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return const MaterialApp(
        // Remove the debug banner
        debugShowCheckedModeBanner: false,
        title: 'Kindacode.com',
        home: HomePage());
  }
}

class HomePage extends StatelessWidget {
  // Create a RadialGradient object
  final Gradient _gradient = const RadialGradient(
    colors: [
      Colors.yellow,
      Colors.deepPurple,
      Colors.red,
      Colors.amber,
      Colors.blue
    ],
    center: Alignment.center,
  );

  const HomePage({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('Kindacode.com'),
      ),
      body: Center(
        // Use ShaderMask to apply the gradient as a mask
        child: ShaderMask(
          blendMode: BlendMode.modulate,
          shaderCallback: (size) => _gradient.createShader(
            Rect.fromLTWH(0, 0, size.width, size.height),
          ),
          child: const Text(
            'A',
            style: TextStyle(
              color: Colors.white,
              fontWeight: FontWeight.bold,
              fontSize: 300,
            ),
          ),
        ),
      ),
    );
  }
}
