Gradient Borders for inputs and Containers In Flutter

Various borders that use gradient instead of boring plain colors.

Usage

Box borders:

Change your container borders to use fancy gradients:

Container(
  width: 100,
  height: 100,
  decoration: BoxDecoration(
    border: const GradientBoxBorder(
      gradient: LinearGradient(colors: [Colors.blue, Colors.red]),
      width: 4,
    ),
    borderRadius: BorderRadius.circular(16)
  ),
),

Works with both: border radius, and with BoxShape.circle

Input borders

You can use GradientOutlineInputBorder as a part of your input decoration:

TextField(
  decoration: InputDecoration(
    border: GradientOutlineInputBorder(
      gradient: LinearGradient(colors: [Colors.red, Colors.blue]),
      width: 2,
    ),
    focusedBorder: GradientOutlineInputBorder(
     gradient: LinearGradient(colors: [Colors.yellow, Colors.green]),
      width: 2
    ),
    label: Text("Example"),
  ),
),

Use this package as a library

Depend on it

Run this command:

With Flutter:

 $ flutter pub add gradient_borders

This will add a line like this to your package's pubspec.yaml (and run an implicit flutter pub get):

dependencies:
  gradient_borders: ^1.0.0

Alternatively, your editor might support flutter pub get. Check the docs for your editor to learn more.

Import it

Now in your Dart code, you can use:

import 'package:gradient_borders/gradient_borders.dart';

example/lib/main.dart

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

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

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

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text("Gradient borders"),
      ),
      body: Center(
        child: Column(
          mainAxisAlignment: MainAxisAlignment.center,
          children: <Widget>[
            Container(
              width: 100,
              height: 100,
              decoration: BoxDecoration(
                  border: const GradientBoxBorder(
                    gradient: LinearGradient(colors: [Colors.blue, Colors.red]),
                    width: 4,
                  ),
                  borderRadius: BorderRadius.circular(16)),
            ),
            const SizedBox(height: 16),
            Container(
              width: 100,
              height: 100,
              decoration: const BoxDecoration(
                border: GradientBoxBorder(
                  gradient:
                      LinearGradient(colors: [Colors.green, Colors.yellow]),
                  width: 4,
                ),
              ),
            ),
            const SizedBox(height: 16),
            Container(
              width: 100,
              height: 100,
              decoration: const BoxDecoration(
                shape: BoxShape.circle,
                border: GradientBoxBorder(
                  gradient:
                      LinearGradient(colors: [Colors.pink, Colors.orange]),
                  width: 4,
                ),
              ),
            ),
            const SizedBox(height: 16),
            const TextField(
              decoration: InputDecoration(
                border: GradientOutlineInputBorder(
                  gradient: LinearGradient(colors: [Colors.red, Colors.blue]),
                  width: 2,
                ),
                focusedBorder: GradientOutlineInputBorder(
                    gradient:
                        LinearGradient(colors: [Colors.yellow, Colors.green]),
                    width: 2),
                label: Text("Example"),
              ),
