Methods
-
dispose(
) → void - Disposes of this camera and all other resources.
-
disposeCamera(
) → void - Closes and releases the camera.
-
init(
TypedSendPort< IsolatePayload< port) → voidIsolatePayload, VideoCommand> > -
Saves the given
TypedSendPort, and creates aTypedReceivePortto send to the parent.inherited -
initCamera(
) → void - Initializes the camera and starts streaming.
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
onData(
VideoCommand data) → void -
A callback to run when new data is received from the parent.
override
-
run(
) → Future< void> -
Runs when the child isolate is spawned, after init is called.
override
-
send(
IsolatePayload obj) → void -
Sends data to the parent.
inherited
-
sendFrame(
OpenCVImage image, {CameraDetails? detailsOverride}) → void - Sends an individual frame to the dashboard.
-
sendFrames(
) → void - Reads frame/s from the camera and sends it/them.
-
sendLog(
LogLevel level, String message) → void - Logs a message by sending a LogPayload to the parent isolate.
-
sendStatus(
[dynamic _]) → void - Sends the current status to the dashboard.
-
start(
) → void - Starts the camera and timers.
-
stop(
) → void - Cancels all timers and stops reading the camera.
-
toString(
) → String -
A string representation of this object.
inherited
-
updateDetails(
CameraDetails newDetails, {bool restart = true}) → void - Updates the camera's details, which will take effect on the next sendFrame call.
