Populating a parent field dynamically in Dart
You should use a ObjectMirror to set a field on your object. Your code tries to set a field on ClassMirror which tries to define a static variable.
class Resource { String name; String description; Resource.map(Map data) { ObjectMirror o = reflect(this); // added ClassMirror c = reflectClass(runtimeType); ClassMirror thisType = c; while(c != null) { for (var k in c.declarations.keys) { print('${MirrorSystem.getName(k)} : ${data[MirrorSystem.getName(k)]}'); if(data[MirrorSystem.getName(k)] != null) { // replace "thisType" with "o" o.setField(k, data[MirrorSystem.getName(k)]); } } c = c.superclass; } }}class Skill extends Resource{ Skill.map(data) : super.map(data);}
Static methods/fields are not inherited in Dart.
There were already some discussions about that behavior here.
You can take a look at the answer to this question in Dart, using Mirrors, how would you call a class's static method from an instance of the class?
If the methods/fields you try to access are not static please provide more code (the classes/objects you are reflecting about)
