Methods

debugDescribeChildren() → List<DiagnosticsNode>

Returns a list of DiagnosticsNode objects describing this node's children.

inherited

debugFillProperties(DiagnosticPropertiesBuilder properties) → void

Add additional properties associated with the node.

inherited

map<TResult extends Object?>({required TResult idle(GenericDataStateIdle value), required TResult loading(GenericDataStateLoading value), required TResult error(GenericDataStateError value), required TResult success(GenericDataStateSuccess value)}) → TResult

Available on GenericDataState, provided by the GenericDataStatePatterns extension

A switch-like method, using callbacks.

mapOrNull<TResult extends Object?>({TResult? idle(GenericDataStateIdle value)?, TResult? loading(GenericDataStateLoading value)?, TResult? error(GenericDataStateError value)?, TResult? success(GenericDataStateSuccess value)?}) → TResult?

Available on GenericDataState, provided by the GenericDataStatePatterns extension

A variant of map that fallback to returning null.

maybeMap<TResult extends Object?>({TResult idle(GenericDataStateIdle value)?, TResult loading(GenericDataStateLoading value)?, TResult error(GenericDataStateError value)?, TResult success(GenericDataStateSuccess value)?, required TResult orElse()}) → TResult

Available on GenericDataState, provided by the GenericDataStatePatterns extension

A variant of map that fallback to returning orElse.

maybeWhen<TResult extends Object?>({TResult idle()?, TResult loading()?, TResult error(Object error)?, TResult success()?, required TResult orElse()}) → TResult

Available on GenericDataState, provided by the GenericDataStatePatterns extension

A variant of when that fallback to an orElse callback.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toDataState<T>(T? successValue) → DataState<T>

Available on GenericDataState, provided by the GenericDataStateExtensions extension

toDiagnosticsNode({String? name, DiagnosticsTreeStyle? style}) → DiagnosticsNode

Returns a debug representation of the object that is used by debugging tools and by DiagnosticsNode.toStringDeep.

inherited

toString({DiagnosticLevel minLevel = DiagnosticLevel.info}) → String

A string representation of this object.

inherited

toStringDeep({String prefixLineOne = '', String? prefixOtherLines, DiagnosticLevel minLevel = DiagnosticLevel.debug, int wrapWidth = 65}) → String

Returns a string representation of this node and its descendants.

inherited

toStringShallow({String joiner = ', ', DiagnosticLevel minLevel = DiagnosticLevel.debug}) → String

Returns a one-line detailed description of the object.

inherited

toStringShort() → String

A brief description of this object, usually just the runtimeType and the hashCode.

inherited

when<TResult extends Object?>({required TResult idle(), required TResult loading(), required TResult error(Object error), required TResult success()}) → TResult

Available on GenericDataState, provided by the GenericDataStatePatterns extension

A switch-like method, using callbacks.

Available on GenericDataState, provided by the GenericDataStatePatterns extension

A variant of when that fallback to returning null

Operators

operator ==(Object other) → bool

The equality operator.
