requestMicAccess method

@override Future<bool?> requestMicAccess()

Request microphone permission. Returns true if permission is granted, false otherwise. Documentation: https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/API/permissions/request Documentation: https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia This is a 'hack' to acquire media permissions. The permissions API is not supported in all browsers.

Implementation

@override
Future<bool?> requestMicAccess() async {
  Logger.logLocalEvent("requesting mic permission");
  try {
    final isSafariOrFirefox = RegExp(r'^((?!chrome|android).)*safari|firefox', caseSensitive: false)
        .hasMatch(_webNavigatorDelegate.userAgent);

    if (isSafariOrFirefox && _webPermissionsDelegate != null) {
      try {
        final result = await _webPermissionsDelegate!.request({"name": "microphone"});
        if (result.state == "granted") return true;
      } catch (e) {
        printDebug("Failed to request microphone permission");
        printDebug(e);
      }
    }

    // Default approach for all browsers (and fallback for Safari & Firefox)
    /// This dirty hack to get media stream. Request (to show permissions popup on Chrome
    /// and other browsers, then stop the stream to release the permission)
    /// TODO(cybex-dev) - check supported media streams
    html.MediaStream mediaStream = await _webMediaDevicesDelegate?.getUserMedia({"audio": true}) ??
        await _webNavigatorDelegate.getUserMedia(audio: true);
    mediaStream.getTracks().forEach((track) => track.stop());
    return hasMicAccess();
  } catch (e) {
    printDebug("Failed to request microphone permission");
    printDebug(e);
    return false;
  }
}
