Cast a variable as a function/method pointer in Dart? (Delegate?)

function methods casting dart

You can use Function as type or if you also want to specify the arguments and return type of these functions you can create typedefs.

Map<String, Function> triggerHandler = {  'x' : (t) => hello(t)};

typedef int SomeName(SomeType arg1);Map<String, SomeName> triggerHandler = {  'x' : (t) => hello(t)};
