You decide to upgrading your Flutter app from version 1.x to 2.x. You upgrade Flutter, your app and all its packages, and you are now ready to run the app.You fire up the app in an emulator or on your device and you met with the following error: Null check operator used on a null value..

I hit a problem when I was trying to re-use named routes once I had already disposed or .pop()'ed them. Since it couldn't really find a satisfactory answer during my searches, I decided to post my answer here, and hopefully it can help someone else...
