This function has a return type of 'Widget', but doesn't end with a return statement.-CodePudding

I have the following warning => This function has a return type of 'Widget', but doesn't end with a return statement. (Documentation) Try adding a return statement, or changing the return type to 'void'.

When I add the return statement in the void function, I encounter the following error:

A value of type 'void' can't be returned from the method 'build' because it has a return type of 'Widget'. (Documentation)

   [...]else if (state is CancelOrderErrorState) {
          showCoreMessageSnackBar(
            CoreMessageWidget.error(title: strings.cancelOrderFailureText.localize(context)),
            autoDismiss: true,
          );
    [...]

Can someone help me fix this return statement?

CodePudding user response：

To expand your code a little bit:

@override
Widget build(BuildContext context) {
...
    else if (state is CancelOrderErrorState) {
          showCoreMessageSnackBar(
            CoreMessageWidget.error(title: strings.cancelOrderFailureText.localize(context)),
            autoDismiss: true,
          );
        return Container(); //<--add this
    }
...
}

You HAVE to return what the method is defined to return which is a Widget. Since the build method is overridden you can't change the return type. Sometimes returning something simple is all you can do.
