fromTypeLink function

OutputType fromTypeLink(TypeLink? typeLink, LibraryReader library)

Creates an AST from code generation from typeLink.

Implementation

o.OutputType fromTypeLink(TypeLink? typeLink, LibraryReader library) {
  if (typeLink == null || typeLink.isDynamic || typeLink.isPrivate) {
    return o.DYNAMIC_TYPE;
  }
  var typeArguments = <o.OutputType>[];
  for (var i = 0; i < typeLink.generics.length; i++) {
    typeArguments.add(fromTypeLink(typeLink.generics[i], library));
  }
  // When `typeLink` represents a type parameter, it doesn't require an import.
  final importUrl = typeLink.import != null
      ? library.pathToUrl(typeLink.import).toString()
      : null;
  var outputType = o.ExternalType(
    CompileIdentifierMetadata(
      name: typeLink.symbol,
      moduleUrl: importUrl,
      typeArguments: typeArguments,
    ),
    typeArguments,
  );
  if (typeLink.isNullable) {
    outputType = outputType.asNullable();
  }
  return outputType;
