iOS 7 style waveform

iOS 9 style waveform

Getting Started

Requirements

• Dart >= 3.0.0
• Flutter >= 3.7.0

Usage

Simply create a SiriWave widget:

import 'package:siri_wave/siri_wave.dart';

class MyWidget extends StatelessWidget {
  Widget build(BuildContext context) {
    return SiriWave();
  }
}

To customize the amplitude, frequency, speed, and color properties of the waveform, create an instance of SiriWaveController and pass it to the SiriWave widget as shown in the code snippet below:

import 'package:siri_wave/siri_wave.dart';

class MyWidget extends StatelessWidget {
  Widget build(BuildContext context) {
    // You can customize the default values of the waveform while creating the
    // controller:
    //  final controller = SiriWaveController(
    //    amplitude: 0.5,
    //    color: Colors.red,
    //    frequency: 4,
    //    speed: 0.15,
    //  );
    final controller = SiriWaveController();
    return SiriWave(controller: controller);
  }
}

Afterward, you can invoke any desired method from the controller to modify the waveform:

controller.setAmplitude(0.8);
controller.setSpeed(0.1);

// These are only available in the iOS 7 style waveform.
controller.setColor(Colors.yellow);
controller.setFrequency(4);

For a complete sample application, please checkout the example.
