Static Methods

asyncSingleton<T>(Future<T> create()) → AsyncSingletonRef<T>

Creates a new AsyncSingletonRef which always return the same instance.

asyncTransient<T>(Future<T> create()) → AsyncTransientRef<T>

Creates a new AsyncTransientRef which always return a new instance.

scoped<T>(CtxCreateFn<T> create, {DisposeFn<T>? dispose, bool autoDispose = true}) → ScopedRef<T>

Creates a new ScopedRef which requires a context to access the instance.

scopedFamily<T, F>(CtxFamilyCreateFn<T, F> create, {DisposeFn<T>? dispose, bool autoDispose = true}) → ScopedFamilyRef<T, F>

Creates a new ScopedFamilyRef which requires a context and family value to access the instance. The family value must be immutable and implement == and hashCode.

singleton<T>(T create()) → SingletonRef<T>

Creates a new SingletonRef which always return the same instance.

transient<T>(T create()) → TransientRef<T>

Creates a new TransientRef which always return a new instance.
