[Android] Browser is not redirecting the user back to the app

I am implementing Google OAuth 2.0 for Flutter Android, but the browser is not redirecting the user back to the app. Do I need deep linking for this, or can I manage it through a custom URI?

I have created **Client ID for Web application** and added same redirect URL [https://companyname.com/api/oauth/google/callback](https://companyname.com/api/oauth/google/callback)
I also added domain [companyname.com](url) on **OAuth consent screen** under Authorized domains

**Here is my code**

**build.gradle**
```
defaultConfig {

manifestPlaceholders += [
appAuthRedirectScheme: 'https'
]
//other config
}
```

**AndroidManifest.xml**
```

```

**Flutter Code**
```
final FlutterAppAuth appAuth = FlutterAppAuth();

final AuthorizationTokenResponse? result =
await appAuth.authorizeAndExchangeCode(
AuthorizationTokenRequest(
'xxxxxxxxxxxx-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.apps.googleusercontent.com',
'https://companyname.com/api/oauth/google/callback',
scopes: ['openid', 'profile', 'email'],
serviceConfiguration: AuthorizationServiceConfiguration(
authorizationEndpoint: 'https://accounts.google.com/o/oauth2/v2/auth',
tokenEndpoint: 'https://oauth2.googleapis.com/token',
),
),
);
```

Start by reviewing build.gradle and AndroidManifest.xml alongside the FlutterAppAuth authorizeAndExchangeCode call and RedirectUriReceiverActivity configuration. Trace the configured redirect URI through the Android intent filter and OAuth request; done means the browser returns to the app and the authorization code exchange completes successfully.
