acceptsType method

@override bool acceptsType(ASTType type)

Will return true if type can be cast to this type. Note: This is similar to Java isInstance and isAssignableFrom.

Implementation

@override
bool acceptsType(ASTType type) {
  // A `dynamic` key/value component acts as a wildcard, so an empty `{}`
  // literal (typed `Map<dynamic,dynamic>`) is assignable to a typed map like
  // `Map<String,int>`. Mirrors how lists ignore their element type here.
  if (type is ASTTypeMap) {
    bool accepts(ASTType a, ASTType b) =>
        a is ASTTypeDynamic || b is ASTTypeDynamic || a.acceptsType(b);
    if (accepts(keyType, type.keyType) &&
        accepts(valueType, type.valueType)) {
      return true;
    }
  }
  return super.acceptsType(type);
}
