fromJson static method

TranslationExport fromJson(Map<String, Object?> json, { String directory = '.', })

Decodes an already-parsed keys.json.

directory is what file will resolve shots against; the default only suits a caller that will not open one.

Implementation

static TranslationExport fromJson(
  Map<String, Object?> json, {
  String directory = '.',
}) {
  var version = _int(json['version']);
  if (version > translationExportVersion) {
    throw FormatException(
      'This export is version $version and this is a reader for '
      '$translationExportVersion. Upgrade the flutterware dependency of '
      'whatever reads it.',
    );
  }
  return TranslationExport(
    version: version,
    directory: directory,
    catalogs: _list(json['catalogs'], ExportedCatalog.fromJson),
    keys: _list(json['keys'], ExportedKey.fromJson),
    findings: switch (json['findings']) {
      Map findings => ExportFindings.fromJson(
        findings.cast<String, Object?>(),
      ),
      _ => const ExportFindings(),
    },
    measuredMaxLengths: json['maxLengths'] is Map,
    maxLengthDevices: switch (json['maxLengths']) {
      Map block => [
        for (var device in block['devices'] as List? ?? const [])
          if (device is String) device,
      ],
      _ => const [],
    },
  );
