I have test application:
import 'dart:mirrors';
class A {
void eventHandlerInt(List<int> x){}
void eventHandlerBool(List<bool> x){}
}
void testMirrors(aFunction){
ClosureMirror mir = reflect(aFunction);
var param = mir.function.parameters.first;
//How to get the Type T of List<T> of the first param?
}
void main() {
var a = new A();
testMirrors(a.eventHandlerInt);
testMirrors(a.eventHandlerBool);
}
I would like to be able to find out what the generic type is of the first parameter of the method passed into testMirrors
, so in the example above it would be int
then bool
. Is this even possible? if I inspect param the type property is null.
List<TypeMirror> types = mir.function.parameters.first.type.typeArguments;
param.forEach((e) => print(e.simpleName));
prints
Symbol("int")
Symbol("bool")
