StarfieldController class

Controller class to add functionality to the starfield.

Each individual star will be generated using the provided configuration. Thenever the an property has changed (e.g. the number), the app must be restarted in order for the StarfieldController to be initialized using the updated configuration.

Constructors

StarfieldController({required int number, required Size size, required double depth, required double velocity, required double scale})
Creates a StarfieldController.

init() → void
Initializes the StarfieldController by creating the Stars.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
