Flutter 3.7.0: Modal bottom sheet Issue

[varenaya]

I tried to run my application in debug mode after upgrading to flutter 3.7.0 from 3.3.9, but was unable to build it due to this issue.

Launching lib\main.dart on sdk gphone x86 in debug mode...

I think you could solve this by adding hide ModalBottomSheetRoute to the import of either package:flutter/material.dart or package:modal_bottom_sheet/modal_bottom_sheet.dart.

tried this but doesn't really work had this same issue in flutter 3.7 beta too.
Also i am only importing package:flutter/material.dart i guess this issue persists with the sdk.

Hi @varenaya
The issue is related to a 3rd party plugin (modal_bottom_sheet) rather than to Flutter itself. Please open the issue in the dedicated repository.

For quick search results, I see there is an existing issue addressing the case you described jamesblasco/modal_bottom_sheet#314, so please follow up on it for further updates.

Closing, as this isn't an issue with Flutter itself.

yeah this was helpful, i happen to be using few packages that were using package:modal_bottom_sheet/modal_bottom_sheet.dart, also found the solution for that too.

I am new to this can you also helm me in this issue, i am trying to build apk but keep getting this error

../../../../../.pub-cache/hosted/pub.dev/modal_bottom_sheet-2.1.2/lib/src/material_with_modal_page_route.dart:4:1: Error: 'ModalBottomSheetRoute' is imported from both 'package:flutter/src/material/bottom_sheet.dart' and 'package:modal_bottom_sheet/src/bottom_sheet_route.dart'.

This is because of the packages you are using in your code which happen to use package:modal_bottom_sheet/modal_bottom_sheet.dart and are not optimize for flutter 3.7.0, hence try to find the packages responsible, upgrade them if their updates are available or downgrade your flutter version.

thanks,
as of ow i bypassed the error by this

dependency_overrides:
modal_bottom_sheet:
git:
url: https://github.com/danReynolds/modal_bottom_sheet.git
path: modal_bottom_sheet

I solved this issue by using their pre-release update
modal_bottom_sheet: ^3.0.0-pre

Hope this helps
