I want to access to a property by the name si string format.
If I have a class like that:
class PrefsState {
String a;
PrefsState({
this.a,
})
How can I do something like that:
PrefsState test= PrefsState(a: "it is a test");
String key = "a";
print(test[key]);
Of course is not working. There is a way to do that in Dart ?
Unfortunately, you cannot use reflection/mirrors in flutter. What you can do, which is tedious, is use maps.
class PrefsState {
String a;
const PrefsState({ this.a, });
dynamic getProp(String key) => <String, dynamic>{
'a' : a,
}[key];
}
It's probably better to build the map in the constructor, but if you want const constructors then you'll have to settle for this. Likely won't make much of a difference unless you have a million parameters anyway. Then you use it like so:
PrefsState test= PrefsState(a: "it is a test");
String key = "a";
print(test.getProp(key));
I don't think there is a less cumbersome way of doing this, but would love to be proven wrong :-)
