In javascript you can do something like this:
var name = 'myVariableName';
myObject[name] = someValue;
In Dart, can I get variables from class objects by their name as a string? For example
var vector = new Vector3();
vector['x'] = 0.0;

2Note: this code doesn't do any kind of casting. You are only setting a property, and property keys are strings.Oriol– Oriol2013-11-17 00:42:18 +00:00Commented Nov 17, 2013 at 0:42

If you want to access normal fields of an arbitrary object through a string you need to use mirrors (reflection). You need to be careful, though, since mirrors can increase the code-size of the dart2js output considerably if not done carefully.
If you just need a string-value store, then a Map is what you are looking for.
