Usage

iOS 7 Siri-style waveform

To create an iOS 7 Siri-style waveform, use the SiriWaveform.ios7() constructor:

import 'package:siri_wave/siri_wave.dart';

class MyWidget extends StatelessWidget {
  Widget build(BuildContext context) {
    return SiriWaveform.ios7();
  }
}

You can customize the waveform by passing a controller and/or options:

class MyWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    final controller = IOS7SiriWaveformController(
      amplitude: 0.5,
      color: Colors.red,
      frequency: 4,
      speed: 0.15,
    );
    return SiriWaveform.ios7(
      controller: controller,
      options: IOS7SiriWaveformOptions(
        height: 180,
        width: 360,
      ),
    );
  }
}

You can also change the properties of the waveform later:

  controller.amplitude = 0.3;
  controller.color = Colors.white;

iOS 9 Siri-style waveform

To create an iOS 9 Siri-style waveform, use the SiriWaveform.ios9() constructor:

import 'package:siri_wave/siri_wave.dart';

class MyWidget extends StatelessWidget {
  Widget build(BuildContext context) {
    return SiriWaveform.ios9();
  }
}

As with the iOS 7 Siri-style waveform, you can customize the waveform by passing a controller and/or options:

class MyWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    final controller = IOS9SiriWaveformController(
      amplitude: 0.5,
      speed: 0.15,
    );
    return SiriWaveform.ios9(
      controller: controller,
      options: IOS9SiriWaveformOptions(
        height: 180,
        width: 360,
      ),
    );
  }
}
