FormProvider
The FormProvider module provides APIs related to the widget provider. You can use the APIs to update a widget, set the next refresh time for a widget, obtain widget information, and request a widget release.
NOTE
The initial APIs of this module are supported since API version 8. Newly added APIs will be marked with a superscript to indicate their earliest API version.

import formProvider from '@ohos.application.formProvider';
Required Permissions
None.
setFormNextRefreshTime
setFormNextRefreshTime(formId: string, minute: number, callback: AsyncCallback<void>): void;
