CachingAssetBundle class abstract

An AssetBundle that permanently caches string and structured resources that have been fetched.

Strings (for loadString and loadStructuredData) are decoded as UTF-8. Data that is cached is cached for the lifetime of the asset bundle (typically the lifetime of the application).

Binary resources (from load) are not cached.

Methods

clear() → void
If this is a caching asset bundle, clear all cached data.
override
evict(String key) → void
If this is a caching asset bundle, and the given key describes a cached asset, then evict the asset from the cache so that the next time it is loaded, the cache will be reread from the asset bundle.
override
load(String key) → Future<ByteData>
Retrieve a binary resource from the asset bundle as a data stream.
inherited
loadBuffer(String key) → Future<ImmutableBuffer>
Retrieve a binary resource from the asset bundle as an immutable buffer.
override
loadString(String key, {bool cache = true}) → Future<String>
Retrieve a string from the asset bundle.
override
loadStructuredBinaryData<T>(String key, FutureOr<T> parser(ByteData data)) → Future<T>
Retrieve bytedata from the asset bundle, parse it with the given function, and return the function's result.
override
loadStructuredData<T>(String key, Future<T> parser(String value)) → Future<T>
Retrieve a string from the asset bundle, parse it with the given function, and return the function's result.
override
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.

toString() → String
A string representation of this object.
