Constructors

LceModel.cacheThenNet(PARAMS params, ServiceSet<DATA, PARAMS> serviceSet, {Stream<LceState<DATA>>? startWith, Logger? logger})
Creates a model that takes a cached value and then reloads from network if nothing cached or cached data is stalled params Params that identify data being loaded serviceSet Data service-set startWith Stream that emits before loading start. logger Logging function

Properties

hashCode → int
The hash code for this object.
no setterinherited
params → PARAMS
Params that identify data being loaded
no setter
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
state → Stream<LceState<DATA>>
Model state. Subscription starts data load for the first subscriber. Whenever last subscriber cancels, the model unsubscribes internal components for data updates
no setterinherited

Methods

map<DATA_2 extends Object>(DATA_2 mapper(DATA data)) → LceModel<DATA_2, PARAMS>

Available on LceModel<DATA, PARAMS>, provided by the LceModelExtension extension

Creates a model wrapper that converts DATA_1 to DATA_2 DATA_2 Resulting data type mapper Data mapper
map<DATA_2 extends Object>(DATA_2 mapper(DATA data)) → LceUseCase<DATA_2>

Available on LceUseCase<DATA>, provided by the LceUseCaseExtension extension

Creates a use-case wrapper that converts DATA_1 to DATA_2 DATA_2 Resulting data type mapper Data mapper
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
refresh() → Future<void>
Requests a refresh of data. Data will be updated asynchronously
inherited
refreshed() → LceUseCase<DATA>

Available on LceUseCase<DATA>, provided by the LceUseCaseExtension extension

Wraps use-case to refresh on each subscription
toString() → String
A string representation of this object.
inherited
withRefresh(Stream refresh) → Stream<LceState<DATA>>

Available on LceUseCase<DATA>, provided by the LceUseCaseExtension extension

Takes the LceUseCase.state of model that is being refreshed each time refresh emits a value Useful when you create a model as a result of mapping of some input (params for example) and the LceUseCase.refresh property becomes invisible for the outside world DATA Source model data type refresh Whenever this stream emits a value, the model is refreshed

Operators

operator ==(Object other) → bool
The equality operator.
