setRootTemplate static method
Sets the root template of the navigation hierarchy. If a navigation hierarchy already exists, CarPlay replaces the entire hierarchy.
-
rootTemplate is a template to use as the root of a new navigation hierarchy. If one exists, it will replace the current rootTemplate. Must be one of the type: CPTabBarTemplate, CPGridTemplate, CPListTemplate, CPInformationTemplate, CPPointOfInterestTemplate, CPSearchTemplate If not, it will throw an TypeError
-
If animated is true, CarPlay animates the presentation of the template, but will be ignored this flag when there isn’t an existing navigation hierarchy to replace.
! CarPlay cannot have more than 5 templates on one screen.
Implementation
static Future<void> setRootTemplate({
required CPTemplate rootTemplate,
bool animated = true,
}) async {
if (rootTemplate is CPTabBarTemplate ||
rootTemplate is CPGridTemplate ||

rootTemplate is CPPointOfInterestTemplate ||
rootTemplate is CPSearchTemplate) {
return FlutterCarPlayController.flutterToNativeModule(
FCPChannelTypes.setRootTemplate, <String, dynamic>{
'rootTemplate': rootTemplate.toJson(),
'animated': animated,
}).then((value) {
if (value == true) {
if (FlutterCarPlayController.templateHistory.isEmpty) {
FlutterCarPlayController.templateHistory.add(rootTemplate);
} else {
FlutterCarPlayController.templateHistory[0] = rootTemplate;
