Creating an ArkTS Widget

You can create a widget in either of the following modes:

When creating a project, select Application. The project created this way does not have a widget by default. You can right-click a module folder and choose New > Service Widget to create a widget.
When creating a project, select Atomic Service. The project created this way has a widget by default. You can right-click a module folder and choose New > Service Widget to create a widget.

WidgetCreateProject >NOTE > >This document is based on DevEco Studio 3.1.1 Release. The actual UI and features may be different if you are using any other version of DevEco Studio.

To create an ArkTS widget in an existing project, perform the following steps:

Right-click a module folder and choose New > Service Widget.

WidgetProjectCreate1 >NOTE > >In a project of API version 10 in the stage model, you can directly create a dynamic or static service widget from the Service Widget menu. After a service widget is created, you can change its type by setting isDynamic in the form_config.json configuration file. If isDynamic is left empty or set to true, the widget is a dynamic widget. If isDynamic is set to false, the widget is a static widget.

Select a widget template based on the actual service scenario.
