Layout Templates for Flutter Web error in NavigationService goBack

You can’t return a void when the function says it’ll return a bool.

Either change the function signature to return a void or remove the return keyword infront of the pop call. OR both.

Hello. Thanks for your videos. The function goBack class NavigationService in project Layout Templates for Flutter Web (part 3) I'm getting an error that says:

{

    "resource": ".../flutter-tutorials/037-advanced-web-navigation/00-starting/lib/services/navigation_service.dart",

    "owner": "dart",

    "code": "return_of_invalid_type",

    "severity": 8,

    "message": "A value of type 'void' can't be returned from method 'goBack' because it has a return type of 'bool'.",

    "source": "dart",

    "startLineNumber": 11,

    "startColumn": 12,

    "endLineNumber": 11,
