I am using Go Router on my flutter project and I noticed that the back button is not presented anymore. Even when I specifically add it I get the following error:

======== Exception caught by gesture =============================================================== The following GoError was thrown while handling a gesture: There is nothing to pop When the exception was thrown, this was the stack: #0 GoRouterDelegate.pop (package:go_router/src/delegate.dart:120:5) #1 GoRouter.pop (package:go_router/src/router.dart:284:21) #2 RecordDetailState.build. (package:random_me/screens/record/detail.dart:70:36) #3 _InkResponseState.handleTap (package:flutter/src/material/ink_well.dart:1072:21) #4 GestureRecognizer.invokeCallback (package:flutter/src/gestures/recognizer.dart:253:24) #5 TapGestureRecognizer.handleTapUp (package:flutter/src/gestures/tap.dart:627:11) #6 BaseTapGestureRecognizer._checkUp (package:flutter/src/gestures/tap.dart:306:5) #7 BaseTapGestureRecognizer.handlePrimaryPointer (package:flutter/src/gestures/tap.dart:239:7)

  Widget build(BuildContext context) {
    AppTranslations.init(context);
    return Scaffold(
      appBar: AppBar(
          title: Text(TRANSLATION.record_detail),
          leading: IconButton(
            onPressed: () {
              GoRouter.of(context).pop();
            },
            icon: Icon(Icons.arrow_back_ios),
            //replace with our own icon data.
          )),

Edit: If I call

GoRouter.of(context).push(CategoryDetail.routeName);

instead of

GoRouter.of(context).go(CategoryDetail.routeName);

it works;

  • The back button is not shown because Gorouter there is no page to go back to. This is also what the error message is telling you. Did you push any page? Can you show code of that? – jraufeisen Jan 28 '23 at 23:39

    Ok I made it work If I call the push method instead of the go method it works GoRouter.of(context).push(CategoryDetail.routeName); – John Jan 28 '23 at 23:41

Fixed: If I call

GoRouter.of(context).push(CategoryDetail.routeName);

instead of

GoRouter.of(context).go(CategoryDetail.routeName);

it works;
