putFileStream abstract method

Future<File> putFileStream(
  1. String url,
  2. Stream<List<int>> source, {
  3. String? key,
  4. String? eTag,
  5. Duration maxAge = const Duration(days: 30),
  6. String fileExtension = 'file',
})
inherited

Put a byte stream in the cache. When using an existing file you can use file.openRead(). It is recommended to specify the eTag and the maxAge. When maxAge is passed and the eTag is not set the file will always be downloaded again. The fileExtension should be without a dot, for example "jpg". When cache info is available for the url that path is re-used. The returned File is saved on disk.

Implementation

Future<File> putFileStream(
  String url,
  Stream<List<int>> source, {
  String? key,
  String? eTag,
  Duration maxAge = const Duration(days: 30),
  String fileExtension = 'file',
});
