Adding TextInputClient.currentAutofillScope property
Summary
#A new getter, TextInputClient.currentAutofillScope
, was added to the
TextInputClient
interface; all TextInputClient
subclasses must
provide a concrete implementation of currentAutofillScope
.
This getter allows the TextInputClient
to trigger an
autofill that involves multiple logically connected input
fields. For example, a "username" field can trigger an
autofill that fills both itself and the "password"
field associated with it.
Context
#On many platforms, autofill services are capable of
autofilling multiple input fields in a single autofill attempt.
For example, username fields and password fields can usually
be autofilled in one go. For this reason, a Flutter input
field that is about to trigger autofill should also provide
the platform with information about other autofillable input
fields logically connected to it.
TextInputClient.currentAutofillScope
defines the group of
input fields that are logically connected to this TextInputClient
,
and can be autofilled together.
Description of change
#TextInputClient
now has an additional getter that returns
the AutofillScope
that this client belongs to.
This getter is used by the input client to collect autofill
related information from other autofillable input fields
within the same scope.
abstract class TextInputClient {
AutofillScope get currentAutofillScope;
}
If you see the error message "missing concrete implementation of 'getter TextInputClient.currentAutofillScope'" while compiling a Flutter app, follow the migration steps listed below.
Migration guide
#If you're not planning to add multifield autofill
support to your TextInputClient
subclass,
simply return null
in the getter:
class CustomTextField implements TextInputClient {
// Not having an AutofillScope does not prevent the input field
// from being autofilled. However, only this input field is
// autofilled when autofill is triggered on it.
AutofillScope get currentAutofillScope => null;
}
If multifield autofill support is desirable, a common
AutofillScope
to use is the AutofillGroup
widget.
To get the closest AutofillGroup
widget to the text
input, use AutofillGroup.of(context)
:
class CustomTextFieldState extends State<CustomTextField> implements TextInputClient {
AutofillScope get currentAutofillScope => AutofillGroup.of(context);
}
