Installation

dependencies:
  animated_border_widgets: ^0.1.0

Quick Start

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

class Demo extends StatefulWidget {
  const Demo({super.key});

  @override
  State<Demo> createState() => _DemoState();
}

class _DemoState extends State<Demo> {
  final controller = AnimatedGradientBorderController();

  @override
  void dispose() {
    controller.dispose();
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    return AnimatedGradientBorder(
      controller: controller,
      borderRadius: BorderRadius.circular(20),
      borderWidth: 1.8,
      colors: const [
        Color(0xFFED7203),
        Color(0xFFFFA726),
        Color(0xFFFFD54F),
        Color(0xFFFFE0B2),
        Color(0xFFFFB74D),
        Color(0xFFFF8A65),
        Color(0xFFED7203),
      ],
      child: SizedBox(
        height: 56,
        child: ElevatedButton(
          onPressed: controller.triggerBoost,
          child: const Text('Boost'),
        ),
      ),
    );
  }
}

Hold Boost Mode

Use holdBoostMode for press-and-hold interactions:

AnimatedGradientBorder(
  holdBoostMode: isPressed,
  holdBoostTurnsPerSecond: 0.9,
  colors: palette,
  child: const SizedBox(height: 52),
)
