call method
Call the name action on the state, with optional data.
The same as action with the data positional, so an actions object reads
like a command: HomePage.actions.call("shake_the_logo", {"times": 3}).
As the method is named call, the object is callable as well:
HomePage.actions("shake_the_logo").
Implementation
void call(String name, [dynamic data]) {
action(name, data: data);
}
