linkTypeOf function

TypeLink linkTypeOf(DartType type)

Returns a TypeLink to the given statically analyzed DartType.

Implementation

TypeLink linkTypeOf(DartType type) {
  // Return void or Null types.
  if (type.isVoid) {
    return TypeLink.$void;
  }
  if (type.isDartCoreNull) {
    return TypeLink.$null;
  }
  // Return dynamic type (no type found or type is unusable/inaccessible).
  //
  // For example, there are missing imports, we are referring to a FunctionType
  // that does not come from a typedef, it is the type of a top-level function
  // and that type was not inferred previously by the analyzer. A more proper
  // fix from Angular would be to support function types (for now dynamic only).
  if (type.isDynamic) {
    return TypeLink.$dynamic;
  }
  type = _resolveBounds(type);
  // Return dynamic type (no type found) after _resolveBounds.
  // Note: with non_nullable, library is never null: we need to check its name.
  if (getTypeName(type) == null) {
    return TypeLink.$dynamic;
  }

  var typeArguments = type.alias?.typeArguments;
  if (typeArguments == null) {
    if (type is InterfaceType) {
      typeArguments = type.typeArguments;
    } else {
      typeArguments = const <DartType>[];

  }

  return TypeLink(
    getTypeName(type)!,
    getTypeImport(type),
    generics: typeArguments.map(linkTypeOf).toList(),
    isNullable: type.nullabilitySuffix == NullabilitySuffix.question,
