Levels to control logging output. Logging can be enabled to include all levels above certain Level. Levels are ordered using an integer value Level.value. The predefined Level constants below are sorted as follows (in descending order): Level.SHOUT, Level.SEVERE, Level.WARNING, Level.INFO, Level.CONFIG, Level.FINE, Level.FINER, Level.FINEST, and Level.ALL.
We recommend using one of the predefined logging levels. If you define your own level, make sure you use a value between those used in Level.ALL and Level.OFF.

- value → int
-
Unique value for this level. Used to order levels, so filtering can exclude messages whose level is under certain value.
final - runtimeType → Type
-
A representation of the runtime type of the object.
