asMap method

Returns this type as a resolvable Map type.

This convenience method attempts to view this ResolvableType as a Map. If this type implements or extends Map, it returns the appropriate ResolvableType. Otherwise, it returns ResolvableType.NONE.

Returns:

• ResolvableType representing this type as a Map
• ResolvableType.NONE if this type is not a Map

Example:

final mapType = ResolvableType.forClass(Map<String, int>);
final listType = ResolvableType.forClass(List<String>);

final mapAsMap = mapType.asMap();
print(mapAsMap != ResolvableType.NONE); // true

final listAsMap = listType.asMap();
print(listAsMap == ResolvableType.NONE); // true

// Useful for Map-specific processing
void processIfMap(ResolvableType type) {
  final asMap = type.asMap();
  if (asMap != ResolvableType.NONE) {
    final keyType = asMap.getKeyType();
    final valueType = asMap.getGeneric([1]);
    print("Map with keys: ${keyType.resolve()?.getType()}");
    print("Map with values: ${valueType.resolve()?.getType()}");
  }
}
