Methods
-
clear(
) → void - Clear all cached instances and all definitions.
-
clearInstances(
) → void - Removes all cached instances, preseving definitions.
-
define<
O> (String key, O instantiator(), [bool cacheValidator(Object o)?]) → void -
Defines instantiator and cache-validator for
key. -
defineAll(
Map< String, dynamic> map) → void -
Define all keys from
map, where map values can be a instantiator functions or a list with 2 values (instantiator and cache-validator functions). -
disposeInstance(
String key) → void -
Removes
keyinstance from cache. -
disposeInstances(
int? amountToRemove) → int -
get<
O> (String key, [O instantiator()?, bool cacheValidator(Object o)?]) → O? -
Returns an object for
key. -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
setCacheValidator<
O> (String key, bool cacheValidator(Object o)) → void -

cacheValidatorforkey -
setInstantiator<
O> (String key, O instantiator()) → void -
Sets the
instantiatorforkey -
toString(
) → String -
A string representation of this object.
