# Windows Single Instance

Restrict a Windows app to only be able to open one instance at a time.

## Installing

1. Add `WidgetsFlutterBinding.ensureInitialized();` to the start of your apps `main` function.

1. Add the `async` modifier to your apps `main` function.

1. Add a call to `WindowsSingleInstance.ensureSingleInstance()`, passing the apps startup args, a custom app string unique to your app (a-z, 0-9, \_ and - only), and an optional callback function.

## Example

```

void main(List args) async {

    WidgetsFlutterBinding.ensureInitialized();

    await WindowsSingleInstance.ensureSingleInstance(

        args,

        "custom_identifier",

        onSecondWindow: (args) {

            print(args);

        });

    runApp(const MyApp());

}

```
