transformToPlatformConstructorArgs method

List transformToPlatformConstructorArgs(List args, List<int> indices, Map<String, dynamic> typeMap, Map<String, dynamic> enumMap, Map<String, dynamic> classMap, String platformVar,)

实例化参数处理 将 pack 过后的 enum / class 转成 android / ios 平台侧的 enum / class

Implementation

List<dynamic> transformToPlatformConstructorArgs(
  List<dynamic> args,
  List<int> indices,
  Map<String, dynamic> typeMap,
  Map<String, dynamic> enumMap,
  Map<String, dynamic> classMap,
  String platformVar,
) {
  if (indices.length == 0) {
    return [];
  }
  List<dynamic> params = [];
  for (int i = 0; i < indices.length; i++) {
    int argsIdx = indices[i];
    String type = typeMap['paramType-$argsIdx'];
    // collectionType genericKind typeName
    String collectionType = type.split(' ')[0];
    String genericKind = type.split(' ')[1];
    String typeName = type.split(' ')[2];
    dynamic arg = args[argsIdx];
    if (arg == null) {
      params.add(null);
      continue;
    }
    // 如果类别是 enum / class 且不是以平台侧 enum / class  传入的话
    // 需要转成 平台侧的 的 enum / class  传递给构造函数
    if (collectionType == '' &&
        genericKind == 'enum' &&
