MediaDevices extension type

The MediaDevices interface of the Media Capture and Streams API provides access to connected media input devices like cameras and microphones, as well as screen sharing. In essence, it lets you obtain access to any hardware source of media data.

Properties

hashCode → int
The hash code for this object.

ondevicechange ↔ EventHandler?
getter/setter pair
runtimeType → Type
A representation of the runtime type of the object.

Methods

addEventListener(String type, EventListener? callback, [JSAny options]) → void
The addEventListener() method of the EventTarget interface sets up a function that will be called whenever the specified event is delivered to the target.
inherited
dispatchEvent(Event event) → bool
The dispatchEvent() method of the EventTarget sends an Event to the object, (synchronously) invoking the affected event listeners in the appropriate order. The normal event processing rules (including the capturing and optional bubbling phase) also apply to events dispatched manually with dispatchEvent().
inherited
enumerateDevices() → JSPromise<JSArray<MediaDeviceInfo>>
The enumerateDevices() method of the MediaDevices interface requests a list of the currently available media input and output devices, such as microphones, cameras, headsets, and so forth. The returned Promise is resolved with an array of MediaDeviceInfo objects describing the devices.
getDisplayMedia([DisplayMediaStreamOptions options]) → JSPromise<MediaStream>
The getDisplayMedia() method of the MediaDevices interface 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.
getSupportedConstraints() → MediaTrackSupportedConstraints
The getSupportedConstraints() method of the MediaDevices interface returns an object based on the MediaTrackSupportedConstraints dictionary, whose member fields each specify one of the constrainable properties the understands.
getUserMedia([MediaStreamConstraints constraints]) → JSPromise<MediaStream>
The getUserMedia() method of the MediaDevices interface prompts the user for permission to use a media input which produces a MediaStream with tracks containing the requested types of media.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
removeEventListener(String type, EventListener? callback, [JSAny options]) → void
The removeEventListener() method of the EventTarget interface removes an event listener previously registered with EventTarget.addEventListener from the target. The event listener to be removed is identified using a combination of the event type, the event listener function itself, and various optional options that may affect the matching process; see Matching event listeners for removal.
inherited
toString() → String
A string representation of this object.

Operators

operator ==(Object other) → bool
The equality operator.
