How to create an Empty Map in Dart - Step by Step Examples

How to create an Empty Map in Dart ?

To create an empty map in Dart, you can use the Map constructor. This creates a new, empty Map object.

We can create an empty map in Dart using the Map constructor, which initializes a map with no key-value pairs.

For example,

We start by declaring a variable named emptyMap. This variable will hold our empty map.
We then use the Map() constructor to create a new, empty Map object. In Dart, the Map() constructor initializes the map with no key-value pairs.
The newly created map is now assigned to the emptyMap variable. In this example, the map has string keys and integer values.
We can now perform various operations on this empty map, such as adding key-value pairs, checking for the presence of keys, and retrieving values.

void main() {
    // Declare an empty map
    Map<String, int> emptyMap = {};

    // Operations on the empty map
    // ...

    print(emptyMap);
}

{}
