DeferredJsonWidgetData class

A JsonWidgetData subclass that does not parse the JSON until the values are needed. This is used internally by the library for when widgets are requested through a variable reference because the variable often won't exist until after the first pass of the widget tree processing is completed.

Methods

build({ChildWidgetBuilder? childBuilder, required BuildContext context}) → Widget

Convenience method that can build the widget this data object represents. This is the equilivant of calling: builder.build and padding this in as the data parameter.

override

copyWith({dynamic args, JsonWidgetBuilder? builder, List<JsonWidgetData>? children, Set<String>? listenVariables, String? id, dynamic originalChild, dynamic originalChildren, JsonWidgetRegistry? registry, String? type}) → JsonWidgetData

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

recreate([JsonWidgetRegistry? newRegistry]) → JsonWidgetData

Recreates the data object based on the updated values and function responces from the registry. This should only be called within the framework itself, external code should not need to call this.

override

toJson() → Map<String, dynamic>

Abstract function that concrete classes must implement. This must encode the internal data model to a JSON compatible representation.

override

toString() → String

A string representation of this object.

Operators

The equality operator.
