Guide on establishing the structure of a map data type in Dart

When working with typescript:

const someMap = {a: "hi", b: 3}; // Typescript can determine the type of someMap as {a:string, b:number}.

const greet = someMap.a; // Typescript identifies greet as a string.

const someMapList: {a:string, b:number}[] = [{a: "hi", b: 3},{a: "bye", b:5}];
someMapList.map((m)=> {
    // Typescript can infer the structure of m.
})

However, when using Dart, the only option I see is Map<K,V>. How can I accomplish the same tasks in Dart?

Answer №1

When working with Typescript/Javascript, maps can be likened to Objects, allowing for the definition of their structure as you are attempting to do. However, in Dart, this is not the case.

To achieve a similar outcome, you will need to create your own Object

class CustomObject {
  final string a;
  final int b;
  
  CustomObject(this.a, this.b);

}
