" Error: Member not found: 'packageRoot' " in Flutter

Question

While trying to run any flutter project on Android Studio, I am getting this particular error :

[+11147 ms] [+13655 ms] ../../flutter/.pub-cache/hosted/pub.dartlang.org/platform-3.0.2/lib/src/interface/local_platform.dart:46:19: Error: Member not found: 'packageRoot'.
[        ] [   +1 ms]       io.Platform.packageRoot; // ignore: deprecated_member_use
[        ] [        ]                   ^^^^^^^^^^^

Looked on the net for quite a while but couldn't find any viable solution. Can anyone help with a fix?

This is a platform related issue and has to do with a dependency used. I advise you run `flutter pub upgrade` to upgrade — connelblaze, Mar 06 '22 at 21:01

Not helpful. I am already on `stable`. – Michał Dobi Dobrzański Feb 06 '22 at 16:44
@MichałDobiDobrzański did you find a fix? – JoseMelendez Feb 07 '22 at 01:28

I was able to fix this by running `flutter doctor` and reading the output. For me, the Visual Studio requirement is now 2019 or above, and I had 2017, after installing VS 2022 and for good measure running `flutter upgrade` `flutter pub upgrade` and `flutter pub outdated` I am now up and running again – Simon Jones Feb 07 '22 at 04:32

@JoseMelendez I think that `flutter pub upgrade` helped me with that - dependencies were out of date. This happened after upgrading to Flutter `2.10` from `2.8`. – Michał Dobi Dobrzański Feb 07 '22 at 09:05

Using `flutter pub upgrade` also helped me. – Larry Aasen Feb 08 '22 at 13:30
using ```flutter pub upgrade --major-versions``` also helped to automatically update & resolve outdated dependencies. – flutter_bee Mar 02 '22 at 09:32

Add this under dependencies => dependencies: platform: ^3.1.0 – Girish Nair Mar 06 '22 at 17:08
The only thing that could help me was to delete the pubspec.lock file from the project folder and only then run flutter clean and then flutter pub get – benten Mar 07 '22 at 08:33
