Flutter FCM token as a global variable

I have already generated a Firebase token inside my app and I need to use it elsewhere in my code but all of the tutorials I have seen don't use it outside the 

FirebaseMessaging.getToken.then((token){
print(token);
})

How can I use this variable elsewhere in my code?

Thanks in advance.

You have two options, First is to save it in SharedPrefs, if you want to store it and use it even after relaunching the application. 

FirebaseMessaging.getToken.then((token){
SharedPreferences prefs = await SharedPreferences.getInstance();
prefs.setString("Token",token);
})

and retrieve it anywhere in the app with 

prefs.getString("Token");

You can also create a static variable in any class and use it but it will be available for only single launch.

class TokenClass {
  static String token = "temp";
}

set and get it using TokenClass.token

You can save in sharedPrefs or you can define global variable in your app.

globals.dart:

library myGlobals.globals;

String token;

and set global variables:

import 'package:PROJECT_NAME/globals.dart' as globals;
FirebaseMessaging.getToken.then((token){
  globals.token = token;
})

and use:

import 'package:PROJECT_NAME/globals.dart' as globals;
print(globals.token)
