LogsModel class
A data model that collects and stores logs from the rover.
The logs are kept in-memory in separate lists for subsystems, video, and autonomy, and are also saved to disk for retroactive debugging. To prevent slowing down the dashboard or consuming too much memory, the in-memory list is limited to maxLogCount, and logs are only saved to disk every saveToFileInterval.

- hasListeners → bool
-
Whether any listeners are currently registered.

Methods
-
addListener(
VoidCallback listener) → void -
Register a closure to be called when the object changes.
inherited
-
clear(
) → void - Clears all the logs from memory (but not from disk).
-
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).
inherited
-
handleLog(
BurtLog log) → void - Sends a log message to be shown in the footer.
-
init(
) → Future< void> -
Initializes any data needed by this model.
override
-
logsForDevice(
Device? device) → ListQueue< BurtLog> ? -
Returns the list of log messages for the corresponding
device -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
notifyListeners(
) → void -
Call all the registered listeners.
inherited
-
removeListener(
VoidCallback listener) → void -
Remove a previously registered closure from the list of closures that are
notified when the object changes.
inherited
-
saveToFile(
dynamic _) → Future< void> - Saves all the logs in saveToFileBuffer to disk.
-
toString(
) → String -
A string representation of this object.
inherited
Operators
-
operator ==(
Object other) → bool -
The equality operator.
inherited
Constants
- saveToFileInterval → const Duration
- How often to save the buffered logs to the log file.
