AutofillGroup class

An AutofillScope widget that groups AutofillClients together.

AutofillClients within the same AutofillScope must be built together, and they be will be autofilled together.

AutofillClients within the same AutofillScope are isolated from other input fields during autofill. That is, when an autofillable TextInputClient gains focus, only the AutofillClients within the same AutofillScope will be visible to the autofill service, in the same order as they appear in autofillClients.

AutofillScope also allows TextInput to redirect autofill values from the platform to the AutofillClient with the given identifier, by calling getAutofillClient.

An AutofillClient that's not tied to any AutofillScope will only participate in autofill if the autofill is directly triggered by its own TextInputClient.

The AutofillGroup widget only knows about AutofillClients registered to it using the AutofillGroupState.register API. Typically, AutofillGroup will not pick up AutofillClients that are not mounted, for example, an AutofillClient within a Scrollable that has never been scrolled into the viewport. To workaround this problem, ensure clients in the same AutofillGroup are built together:

An example form with autofillable fields grouped into different AutofillGroups.
