HookContextMixin mixin
Mixin with common parts of HookContext implementations.
This mixin should be used by all HookContext implementations. Implementations should only override HookContext.markNeedsBuild and call wrapBuild, triggerPostBuildCallbacks and disposeHooks as needed.

Properties
- debugDoingBuild → bool
-
no setter
- hashCode → int
-
The hash code for this object.
no setterinherited
- mounted → bool
-
Whether this HookContext is still valid.
no setteroverride
- runtimeType → Type
-
A representation of the runtime type of the object.

Methods
-
addPostBuildCallback(
void callback()) → void -
Registers
callback
to be called after the current build.override -
debugDescribeChildren(
) → List< DiagnosticsNode> -
Returns a list of DiagnosticsNode objects describing this node's
children.
override
-
debugFillProperties(
DiagnosticPropertiesBuilder properties) → void -
Add additional properties associated with the node.
override
-
debugMarkWillReassemble(
) → void - Marks the next build as a reassemble, allowing hooks to be added or removed.
-
disposeHooks(
) → void - Disposes all hooks in this HookContext and marks is as unmounted.
-
getUnsafe(
Type type, {bool? watch}) → dynamic -
Retrieves the value of the requested
type
and optionally watches for its change. Returned values are guaranteed to be of typetype
or valueNotFound when it isn't found. Ifwatch
is not set, implementation should perform an educated guess (e.g. based on whether it's called during a build). Exact meaning of "watching" depends on the implementation and may not be supported.inherited -
markNeedsBuild(
) → void -
Requests that this HookContext should be rebuilt.
inherited
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
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}) → 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
-
triggerPostBuildCallbacks(
) → void - Triggers all callbacks registered in the previous build.
-
use<
T> (Hook< T> hook) → T -
Registers
hook
in this HookContext and returns its value.override -
wrapBuild<
T> (T build()) → T -
Performs
build
in this HookContext.
Operators
-
operator ==(
Object other) → bool -
The equality operator.
