Typed Maps - like interfaces in TypeScript

[KoTTi97]

I would love to see typed Maps in Dart/Flutter like it is possible in TypeScript.

TypeScript example:

interface IPerson {
    name: string;
    age: number;
    height?: number;
}

const person: IPerson = {
    name: "Max",
    age: 26
}

I wish Dart/Flutter would support something like that so i do not have to create a class for it. It could look something like this:

interface IPerson {
  String name;
  int age;
  height? double;
}

Map<IPerson> person = {
  name: "Max",
  age: 26,
}

This sort of language level feature request would be better suited for github.com/dart-lang/language/issues
