JsonRadioBuilder class

Builder that can build an Radio See the fromDynamic for the format. Unlike other form fields, this requires the id for the radio variable to be inside of the args. This is because no two widgets can share the same overall id.

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
Builds the widget to render to the tree. If enabled property is true then this will attach the selected value to the JsonWidgetRegistry using the id as the key any time the selected value is changed.
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
Removes any / all values this builder may have set from the JsonWidgetRegistry.
override
toString() → String
A string representation of this object.

Operators

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

Static Methods

fromDynamic(dynamic map, {JsonWidgetRegistry? registry}) → JsonRadioBuilder?
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
