arrangeJsonFilesBySection function

Map<String, dynamic> arrangeJsonFilesBySection(String tokenFileDirectory)

Loads all the design token info into a single structure resulting in something that looks like it would if it was all in one file

Creates a single JSON strcture from the driven by the $metadata.json Adds the $metadata.json and $themes.json with pathing adjusted to in-memory

Implementation

Map<String, dynamic> arrangeJsonFilesBySection(String tokenFileDirectory) {
  // each element of the token set is in this map keyed by the file name ish
  final mergedTokenSet = <String, dynamic>{};

  // load the metadata contents and massage the paths to be map paths
  final metadataContents = json.decode(
    File('$tokenFileDirectory/\$metadata.json').readAsStringSync(),
  );
  mergedTokenSet['\$metadata'] = metadataAsSection(metadataContents as Map<String, dynamic>);

  // Load the themes and msassage the paths to the  contents to be map paths
  final themesContents = json.decode(
    File('$tokenFileDirectory/\$themes.json').readAsStringSync(),
  );
  mergedTokenSet['\$themes'] = themesAsSection(themesContents as List<dynamic>);

  // Iterate across the "tokenSetOrder" in the $metadata file and
  // Has to be the original file locations because they include paths
  // load the json files into their own sections in the map
  for (final onePath in metadataContents['tokenSetOrder'] as List<dynamic>) {
    final fullPath = '$tokenFileDirectory/$onePath.json';
    final contents = jsonDecode(File(fullPath).readAsStringSync()) as Map<String, dynamic>;
    mergedTokenSet[basename(onePath as String)] = contents;
  }
  return mergedTokenSet;
