loadString method

Future<String> loadString (
  1. String key,
  2. {bool cache: true}

Retrieve a string from the asset bundle.

Throws an exception if the asset is not found.

If the cache argument is set to false, then the data will not be cached, and reading the data may bypass the cache. This is useful if the caller is going to be doing its own caching. (It might not be cached if it's set to true either, that depends on the asset bundle implementation.)


Future<String> loadString(String key, { bool cache = true }) async {
  final ByteData data = await load(key);
  if (data == null)
    throw FlutterError('Unable to load asset: $key');
  if (data.lengthInBytes < 10 * 1024) {
    // 10KB takes about 3ms to parse on a Pixel 2 XL.
    // See: https://github.com/dart-lang/sdk/issues/31954
    return utf8.decode(data.buffer.asUint8List());
  return compute(_utf8decode, data, debugLabel: 'UTF8 decode for "$key"');
