visitSource method

@override Uint8List visitSource(ASTSource unit)

Implementation

@override

  final bytesBuilder = BytesBuilder();
  bytesBuilder.addByte(OpCode.file);
  // if the relativeName is null then it is the entry file of this module.
  bytesBuilder.add(_identifier(unit.fullName));
  bytesBuilder.addByte(unit.resourceType.index);
  // final convertedNodes = _convertPossibleAwaitedBlockToCallBack(unit.nodes);
  // for (final node in convertedNodes) {
  // Hoist import & export declarations to the start of the file,
  // so that the file namespace's imports are resolved before any
  // other statement executes, regardless of their positions in source.
  for (final node in unit.nodes) {
    if (node is ImportExportDecl) {
      final bytes = compileAST(node);
      bytesBuilder.add(bytes);
