[Question] - how to get Constructor arguments?

[dinbtechit]

Hi, How to get the list of constructor arguments? to dynamically create the instance..

Annotations:

class Component extends Reflectable {...}
class Injectable extends Reflectable {...}
// Usage

@Injectable()
class ServiceA {}

@Injectable()
class ServiceB { }

@Component()
class MyWidget {
  MyWidget(ServiceA serviceA, ServiceB serviceB);  // <---<< How to access these two parameters
}

Somewhere the code, Logic for the Annotation

var componentClassMirror = const Component().annotatedClasses.first;

// Q. How to get the list of constructor arguments? 
// To pass them in the below method to create an instance of the class
var instanceOfComponent = componentClassMirror.newInstance('',  [ ???])

Here's an example showing how to use the source code exploration part of the mirror system to find information about function declarations, including constructor declarations, and their parameters: https://github.com/google/reflectable.dart/blob/master/test_reflectable/test/declarations_test.dart.

This would allow you to take the componentClassMirror.declarations and search for constructors, look up their parameters, and inspect the type of any given parameter.
