Methods
-
build(
{required ChildWidgetBuilder? childBuilder, required BuildContext context, required JsonWidgetData data}) → Widget -
Builds the widget. If there are dynamic keys on the
data
object, and the widget is not a PreferredSizeWidget, then the returned widget will be wrapped by a stateful widget that will rebuild if any of the dynamic args change in value.inherited -
buildCustom(
{ChildWidgetBuilder? childBuilder, required BuildContext context, required JsonWidgetData data, Key? key}) → Widget -
Custom builder that subclasses must override and implement to return the
actual Widget to be placed on the tree.
override
-
getChild(
JsonWidgetData? data, {int index = 0}) → JsonWidgetData -
Returns a non-null child for widgets that must always have child widgets.
This allows the widget to be built and rendered even if the child is
missing.
inherited
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
remove(
JsonWidgetData data) → void -
Called when a JSON widget is removed from the tree due to a conditional.
Custom widgets may need to implement this to clean up values that may have
been placed on the JsonWidgetRegistry by the widget.
inherited
-
toString(
) → String -
A string representation of this object.
inherited
Operators
-
operator ==(
Object other) → bool -
The equality operator.

Static Methods
-
fromDynamic(
dynamic map, {JsonWidgetRegistry? registry}) → JsonMaterialBuilder? - Builds the builder from a Map-like dynamic structure. This expects the JSON format to be of the following structure:
Constants
- kNumSupportedChildren → const int
- type → const String
