Issue on release mode.

With 0.0.1 this library is working but when I run the exe file built again it spawns a hidden process, another one if you open it again and again.

So I tried upgrading in higher versions but it only works on debug mode. After I built it on windows or run in release mode this error shows.

[ERROR:flutter/runtime/dart_vm_initializer.cc(40)] Unhandled Exception: type 'int' is not a subtype of type 'Map<String, dynamic>' #0 FlutterSingleInstance.isFirstInstance (package:flutter_single_instance/flutter_single_instance.dart:112) <asynchronous suspension>

this is the part of the lib its pointing to
_instance = Instance.fromJson(jsonDecode(data));

also tried to show the runTimeType but still give me error in release, but in the debug it is bool and is ok, so possible that its a lib issue?

logger.d((await FlutterSingleInstance().isFirstInstance()).runtimeType);

you may have to delete the pid file after upgrading, I will issue a fix soon. As a workaround until then you can try to delete the pid file (it should be at C:\Users\<YourUsername>\AppData\Local\Temp\<packagename>.pid)

Thank you, it worked! It runs now on release mode.

The issue with the same process runs in background without the UI if I run the exe file again, is my fault. I didn't add the exit(0).

Closing in favor of #6
