Installation Instructions

Use this package as a library by depending on it

Run this command:

  • With Flutter:
$ flutter pub add app_wrapper

This will add a line like this to your package's pubspec.yaml (and run an implicit dart pub get):

  app_wrapper: ^0.2.2

Alternatively, your editor might support flutter pub get. Check the docs for your editor to learn more.


Import it like so:

import 'package:app_wrapper/app_wrapper.dart';


Lets take a look at how to use AppWrapper to hook up a your application.

class YourApp extends StatelessWidget {
  const YourApp({ Key? key }) : super(key: key);

  Widget build(BuildContext context) {
    return AppWrapper(
      appName: appName,
      eventBus: EventBus(),
      graphQLClient: GraphQlClient(
      appContexts: <your_app_Contexts>,
      child: YourAppEntryWidget(),

With the above snippet, we have successfully hooked up our app to use AppWrapper. Your application's element tree now has access to DeviceCapabilities, graphQLClient etc, that is passed down. These include Device Camera, Device BiometricType (face or fingerprint) and Endpoints.

Provided here is a more detailed snippet, on how to use the package.
