Dartlang mirrors new instance
In Dart, mirrors
is a package that provides a way to inspect and manipulate the runtime behavior of Dart programs. One of the key features of mirrors
is the ability to create new instances of classes.
To create a new instance of a class using mirrors
, you can use the reflectClass
function, which returns a ClassMirror
object that represents the class. You can then use the newInstance
method of the ClassMirror
object to create a new instance of the class.
Here is an example:
import 'package:mirrors/mirrors.dart';
void main() {
// Get the ClassMirror for the MyClass class
ClassMirror myClassMirror = reflectClass(MyClass);
// Create a new instance of MyClass
Object myObject = myClassMirror.newInstance();
}
In this example, reflectClass(MyClass)
returns a ClassMirror
object that represents the MyClass
class. The newInstance
method of the ClassMirror
object is then used to create a new instance of MyClass
.
You can also pass arguments to the constructor of the class when creating a new instance using newInstance
. For example:
Object myObject = myClassMirror.newInstance([arg1, arg2,...]);
This will create a new instance of MyClass
with the specified arguments.
Note that mirrors
is a powerful package that allows you to inspect and manipulate the runtime behavior of Dart programs. However, it is also a complex package that requires a good understanding of the Dart language and its runtime behavior.
