Debug flutter app

If you want to remove something from code in flutter in different modes you have different constants:

• kDebugMode – true if app is in debug mode otherwise false
• kReleaseMode – true if app is in release mode otherwise false
• kProfileMode – true if app is in profile mode otherwise false

And then you can use it like that:

if (kDebugMode) {
   // some code
}

so compiler remove this unused code in other modes.
