findTokens method

Map<String, Token> findTokens(String parent, Map<String, dynamic> input, [ String? groupType ])

Implementation

Map<String, Token> findTokens(
  String parent,
  Map<String, dynamic> input, [
  String? groupType,
]) {
  final tokens = <String, Token>{};

  if (input.containsKey('value')) {
    final cleaned =
        parent.substring(0, parent.length - 1); // remove the trailing dot
    final name = cleaned.split('.').last;

    final end = cleaned.length - name.length - 1;
    final path = end > 0 ? cleaned.substring(1, end) : '';
    final token = Token(
      value: input['value'],
      type: input['type'] as String? ?? groupType,
      path: path,
      name: name,
      extensions: input['\$extensions'] as Map<String, dynamic>?,
    );

    return {
      [path, name].where((e) => e.isNotEmpty).join('.'): token,
    };
  }

  for (var entry in input.entries) {
    final key = entry.key;
    final value = entry.value;

    if (value is Map<String, dynamic>) {
      tokens.addAll(

      );
    }
  }
