# Class FlutterMutatorsStack.FlutterMutator

java.lang.Object
io.flutter.embedding.engine.mutatorsstack.FlutterMutatorsStack.FlutterMutator

Enclosing class:
  FlutterMutatorsStack

public class FlutterMutatorsStack.FlutterMutator extends Object
A class represents a mutator

A mutator contains information of a single mutation operation that can be applied to a `PlatformView`. See `FlutterMutatorsStack.FlutterMutator` for informations on Mutators.
