registerCustomBuilder method
Registers the widget type with the registry to that type
can be used in
custom forms. Types registered by the application take precidence over
built in registered builders. This allows an application the ability to
provide custom widgets even for built in form types.
If the container
has an associated schema id then in DEBUG builds, that
schema will be used to validate the attributes sent to the builder.
Implementation
void registerCustomBuilder(
String type,
JsonWidgetBuilderContainer container,
) =>
_builders[type] = container;
