Methods
-
enumerateDevices(
) → Future< List< MediaDeviceInfo> > - Returns a List of MediaDeviceInfo describing the devices.
-
getDisplayMedia(
Map< String, dynamic> mediaConstraints) → Future<MediaStream> - Calling this method will prompts the user to select and grant permission to capture the contents of a display or portion thereof (such as a window) as a MediaStream. The resulting stream can then be recorded using the MediaStream Recording API or transmitted as part of a WebRTC session.
-
getSources(
) → Future< List> -
getSupportedConstraints(
) → MediaTrackSupportedConstraints - Returns MediaTrackSupportedConstraints recognized by a User Agent for controlling the Capabilities of a MediaStreamTrack object.
-
getUserMedia(
Map< String, dynamic> mediaConstraints) → Future<MediaStream> - Calling this method will prompts the user to select and grant permission to capture the contents of a display or portion thereof (such as a window) as a MediaStream. The resulting stream can then be recorded using the MediaStream Recording API or transmitted as part of a WebRTC session.
