Static Methods

cacheFont(String url, {required int maxCacheObjects, required Duration cacheStalePeriod}) → Future<FileInfo>

Downloads and caches font from the url with the given configuration.

cacheFontStream(String url, {required int maxCacheObjects, required Duration cacheStalePeriod, required DownloadProgressListener? progressListener}) → Stream<FileInfo>

Downloads and caches font from the url with the given configuration. A single FileInfo object is returned as a stream and the download progress is can be listened to using the progressListener callback.

canLoadFont(String url) → Future<bool>

Checks whether the given url can be loaded directly from cache.

custom({required CacheManager cacheManager, bool force = false}) → void

Accepts cacheManager and force to provide a custom CacheManager for testing.

loadCachedFamily(List<String> urls, {required String fontFamily, FontLoader? fontLoader}) → Future<Iterable<FileInfo>>

Fetches the given urls from cache and loads them into the engine to be used.

loadCachedFamilyStream(List<String> urls, {required String fontFamily, required ItemCountProgressListener? progressListener, FontLoader? fontLoader}) → Stream<FileInfo>

Fetches the given urls from cache and loads them into the engine to be used. A stream of FileInfo objects is returned, which emits the font files as they are loaded. The total number of files returned corresponds to the number of urls provided. The download progress can be listened to using progressListener.

loadCachedFont(String url, {required String fontFamily, FontLoader? fontLoader}) → Future<FileInfo>

Fetches the given url from cache and loads it as an asset.

removeCachedFont(String url) → Future<void>

Removes the given url can be loaded directly from cache.
