Windows Single Instance #
Restrict a Windows app to only be able to open one instance at a time.
Installing #

Add WidgetsFlutterBinding.ensureInitialized(); to the start of your apps main function.
Add the async modifier to your apps main function.
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<String> args) async {
WidgetsFlutterBinding.ensureInitialized();
await WindowsSingleInstance.ensureSingleInstance(
args,
"custom_identifier",
onSecondWindow: (args) {
print(args);
});
runApp(const MyApp());
}
