AutonomyModel class

A view model for the autonomy page to render a grid map.

Shows a bird's-eye map of where the rover is, what's around it, where the goal is, and the path to get there. This class uses AutonomyData to keep track of the data as reported by the rover. The grid is a 2D map of width and height gridSize that keeps the roverPosition in the center (by keeping track of its offset) and filling the other cells with AutonomyCells.

Constructors

AutonomyModel(): Listens for incoming autonomy or position data.

Properties

badAppleAudioPlayer → AudioPlayer: The audio player for the Bad Apple music
final
badAppleFrame ↔ int: Which frame in the Bad Apple video we are up to right now
getter/setter pair
badAppleTimer ↔ Timer?: A timer to update the map for every frame of Bad Apple
getter/setter pair
data ↔ AutonomyData: The autonomy data as received from the rover.
getter/setter pair
empty → List<List<(GpsCoordinates, AutonomyCell)>>: An empty grid of size gridSize.
no setter
grid → List<List<(GpsCoordinates, AutonomyCell)>>: The grid of size gridSize with the rover in the center, ready to draw on the UI.
no setter
gridSize ↔ int: The amount of blocks in the width and height of the grid.
getter/setter pair
hashCode → int: The hash code for this object.
no setterinherited
hasListeners → bool: Whether any listeners are currently registered.
no setterinherited
isPlayingBadApple ↔ bool: Whether the UI is currently playing Bad Apple
getter/setter pair
markerBuilder ↔ GpsBuilder: The view model to edit the coordinate of the marker.
getter/setter pair
markers ↔ List<GpsCoordinates>: A list of markers manually placed by the user. Useful for the Extreme Retrieval Mission.
getter/setter pair
offset ↔ GridOffset: The offset to add to all other coordinates, based on roverPosition. See recenterRover.
getter/setter pair
roverHeading → double: The rover's heading

Methods

addListener(VoidCallback listener) → void: Register a closure to be called when the object changes.
inherited
clearMarkers() → void: Deletes all the markers in markers.
dispose() → void: Discards any resources used by the object. After this is called, the object is not in a usable state and should be discarded (calls to addListener will throw after the object is disposed).
override
gpsToBlock(double value) → int: Converts a decimal GPS coordinate to an index representing the block in the grid.
init() → Future<void>: Initializes the view model.
markCell(List<List<(GpsCoordinates, AutonomyCell)>> list, GpsCoordinates gps, AutonomyCell value) → void: Calculates a new position for gps based on offset and adds it to the list.
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void: Call all the registered listeners.
inherited
onNewData(AutonomyData value) → void: A handler to call when new data arrives. Updates data and the UI.
placeMarker() → void: Places the marker in markerBuilder.
placeMarkerOnRover() → void: Places a marker at the rover's current position.
recenterRover() → void: Determines the new offset based on the current roverPosition.
removeListener(VoidCallback listener) → void: Remove a previously registered closure from the list of closures that are notified when the object changes.
inherited
startBadApple() → Future<void>: Starts playing Bad Apple.
stopBadApple() → void: Stops playing Bad Apple and resets the UI.
toString() → String: A string representation of this object.
inherited
updateMarker(GpsCoordinates gps) → void: Removes a marker in gps
zoom(int newSize) → void: Zooms in or out by modifying gridSize.

Operators

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

Constants

badAppleFps → const int: How many frames in a second are being shown
badAppleLastFrame → const int: The last frame of Bad Apple
