ErrorBoundaryState class
Backing state for ErrorBoundary, exposing guard helpers to descendants.
- Inheritance
-
- Object
- State<
ErrorBoundary> - ErrorBoundaryState
Constructors
- ErrorBoundaryState()
- Default constructor; prefer using ErrorBoundaryState.of to obtain instances.
- ErrorBoundaryState.of(BuildContext context)
-
Obtain the nearest ErrorBoundary state to guard operations conveniently.

Methods
-
activate(
) → void -
Called when this object is reinserted into the tree after having been
removed via deactivate.
inherited
-
build(
BuildContext context) → Widget -
Describes the part of the user interface represented by this widget.
override
-
deactivate(
) → void -
Called when this object is removed from the tree.
inherited
-
debugFillProperties(
DiagnosticPropertiesBuilder properties) → void -
Add additional properties associated with the node.
inherited
-
didChangeDependencies(
) → void -
Called when a dependency of this State object changes.
inherited
-
didUpdateWidget(
covariant ErrorBoundary oldWidget) → void -
Called whenever the widget configuration changes.
inherited
-
dispose(
) → void -
Called when this object is removed from the tree permanently.
inherited
-
guardAsyncCallback(
Future< void> action(), {String? source, FutureOr<void> onError(BaseException e)?}) → AsyncCallback - Wrap an async callback to capture errors.
-
guardCallback(
VoidCallback action, {String? source, FutureOr< void> onError(BaseException e)?}) → VoidCallback - Wrap a synchronous callback (e.g., onTap) to capture thrown errors.
-
guardFuture<
T> (Future< T> action(), {String? source, FutureOr<void> onSuccess(T value)?, FutureOr<void> onError(BaseException e)?}) → Future<T> - Guard an async operation and route failures into this boundary.
-
guardStream<
T> (Stream< T> source, {String? sourceName, FutureOr<void> onError(BaseException e)?}) → Stream<T> - Transform a stream so errors are captured by this boundary.
-
initState(
) → void -
Called when this object is inserted into the tree.
inherited
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
reassemble(
) → void -
Called whenever the application is reassembled during debugging, for
example during hot reload.
inherited
-
setState(
VoidCallback fn) → void -
Notify the framework that the internal state of this object has changed.
inherited
-
show(
BaseException error) → void - Programmatically show an error in this boundary (e.g., from state).
-
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
-
toStringShort(
) → String -
A brief description of this object, usually just the runtimeType and the
hashCode.
inherited
Operators
-
operator ==(
Object other) → bool -
The equality operator.
