AudioCache class
This class represents a cache for Local Assets to be played.
On desktop/mobile, Flutter can only play audios on device folders, so first this class copies the files to a temporary folder, and then plays them. On web, it just stores a reference to the URL of the audio, but it gets preloaded by making a simple GET request (the browser then takes care of caching).
You can pre-cache your audio, or clear the cache, as desired.
Constructors
- AudioCache({String prefix = 'assets/', AudioPlayer? fixedPlayer, bool respectSilence = false, bool duckAudio = false})
Properties
- duckAudio ↔ bool
-
This flag should be set to true, if player is used for playing sound while there may be music
getter/setter pair
- fixedPlayer ↔ AudioPlayer?
-
This is an instance of AudioPlayer that, if present, will always be used.
getter/setter pair
- hashCode → int
-
The hash code for this object.

-
loadedFiles
↔ Map<
String, Uri> -
A reference to the loaded files absolute URLs.
getter/setter pair
- prefix ↔ String
-
This is the path inside your assets folder where your files lie.
getter/setter pair
- respectSilence ↔ bool
-
This flag should be set to true, if player is used for playing internal notifications
getter/setter pair
- runtimeType → Type
-
A representation of the runtime type of the object.

Methods
-
clear(
Uri fileName) → Future< void> -
Clears the cache for the file
fileName
. -
clearAll(
) → Future< void> - Clears the whole cache.
-
fetchToMemory(
String fileName) → Future< Uri> -
load(
String fileName) → Future< Uri> -
Loads a single
fileName
to the cache. -
loadAll(
List< String> fileNames) → Future<List< Uri> > -

fileNames
provided to the cache. -
loadAsFile(
String fileName) → Future< File> -

fileName
to the cache but returns it as a File. -
loop(
String fileName, {double volume = 1.0, bool? isNotification, PlayerMode mode = PlayerMode.MEDIA_PLAYER, bool stayAwake = false}) → Future< AudioPlayer> - Like play, but loops the audio (starts over once finished).
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
