isCastedMap method

bool isCastedMap(Object? o)

Returns true if o is a Map<K,V> where K is arguments0 T and V is arguments1 T.

• K or V should be valid. See isValidGenericType.
• This TypeInfo should be a Map. See isMap.

Implementation

bool isCastedMap(Object? o) {
  if (!isMap || o is! Map) return false;

  var arg0 = arguments0;
  var arg1 = arguments1;

  var arg0Ok = arg0 != null && arg0.isValidGenericType;
  var arg1Ok = arg1 != null && arg1.isValidGenericType;

  if (arg0Ok && arg1Ok) {
    return arg0.callCasted(<K>() {
      return arg1.callCasted(<V>() => o is Map<K, V>);
    });
  } else if (arg0Ok) {
    return arg0.callCasted(<K>() => o is Map<K, dynamic>);
  } else if (arg1Ok) {
    return arg1.callCasted(<V>() => o is Map<dynamic, V>);
  } else {
    return false;
  }
