Introduction:
The demo video below shows how to create an autofill username & password in Flutter and how an autofill username & password in your Flutter applications. When you enable autofill, at whatever point the user logs in, the application will show a dialog to save the username and password in a browser and store the credentials in a password manager. It will be shown on your device.
Demo Module::
Code Implement:
Create a new dart file called main.dart inside the lib folder.
In the main .dart file. We will create a new class AutofillDemo(). In this class, we will define a Container widget on a body. Inside the widget, we will add the AutofillGroup() method. In this method, we will add the Column widget.
Container(
padding: const EdgeInsets.all(30),
child: AutofillGroup(
child: Center(
child: Column(
children: [
const SizedBox(
height: 30,
),
Image.asset(
"assets/images/logo.png",
height: 100,
),
const SizedBox(
height: 30,
),
const TextField(
autofillHints: [AutofillHints.username],
decoration: InputDecoration(hintText: "Username"),
),
const SizedBox(
height: 10,
),
const TextField(
obscureText: true,
autofillHints: [AutofillHints.password],
decoration: InputDecoration(hintText: "Password"),
),
const SizedBox(
height: 30,
),
ElevatedButton(
onPressed: () {
TextInput.finishAutofillContext();
Navigator.pushReplacement(context,
MaterialPageRoute(builder: (context) {
return const HomeScreen();
}));
},
child: const Text("Log In"))
],
),
)),
)In this widget, we will add two TextFields for Username and Password with autofillHints. Also, we will create an ElevatedButton(). In this button, we will add TextInput.finishAutofillContext(); for password save, and navigate to the home screen and wrap to the onPressed() function. Also, we will add the text “Log In”.
When we run the application, we ought to get the screen’s output like the underneath screen capture.
The same dart file called main.dart inside the lib folder.
In the main .dart file. We will create a new class HomeScreen(). In this class, we will define a Column widget on a body. In this widget, we will add an image and ElevatedButton() for logout.
Column(
crossAxisAlignment: CrossAxisAlignment.center,
mainAxisAlignment: MainAxisAlignment.center,
children: [
Image.asset(
"assets/images/logo.png",
height: 100,
),
const SizedBox(
height: 100,
),
ElevatedButton(
onPressed: () {
Navigator.pushReplacement(context,
MaterialPageRoute(builder: (context) {
return const AutofillDemo();
}));
},
child: const Text("Log Out"))
],
),When we run the application, we ought to get the screen’s output like the underneath screen capture.
