StreamAudioWaveformTheme class

Applies an audio waveform theme to descendant StreamAudioWaveform and StreamAudioWaveformSlider widgets.

Wrap a subtree with StreamAudioWaveformTheme to override waveform styling. Access the merged theme using BuildContext.streamAudioWaveformTheme.

{@tool snippet}

Override waveform colors for a specific section:

StreamAudioWaveformTheme(
  data: StreamAudioWaveformThemeData(
    color: Colors.grey,
    progressColor: Colors.blue,
    activeThumbColor: Colors.blue,
    activeThumbBorderColor: Colors.blue,
    idleThumbColor: Colors.grey,
    idleThumbBorderColor: Colors.grey,
  ),
  child: StreamAudioWaveformSlider(
    waveform: waveformData,
    onChanged: (value) {},
  ),
)

{@end-tool}
