get method

V? get(
  1. K key, {
  2. V? defaultValue,
})

A type-checked version of operator [] that additionally supports returning a default value.

Returns defaultValue if the key is not found. This is slightly different from map[key] ?? defaultValue if the Map stores null values.

Implementation

//
// Remove if implemented upstream:
// https://github.com/dart-lang/sdk/issues/37392
V? get(K key, {V? defaultValue}) =>
    this.containsKey(key) ? this[key] : defaultValue;
