"Flutter upgrade"

IDX is using an outdated version of Flutter (3.13.4). We are currently on version 3.16.3. How can we update it?

    same to me also, but also need to update the Android SDK, its give me a lot of errors and most of the new package need SDK of 34

    @Glenford Williams - It worked for me.

    I found the way to change flutter SDKs.

    1. open '.idx/dev.nix' file.

    2. edit channel to "unstable"
    channel = "unstable";

    3. edit packages name to pkgs.flutter316
    packages = [
    pkgs.flutter316
    pkgs.nodePackages.firebase-tools
    pkgs.jdk17
    ];

    4. Click right bottom button - Rebuild Environment

    Now it's SDK 3.16.7 version. I don't know how to choose exact 3.16.3 SDK version.
    But it will help you.

    There's few other versions such as flutter319, flutter313, etc.

    You can find nix packages below link.

    Is there a work around?

    I thought i'd be able to get it working using flutter316 from the nix unstable branch but setting channel to "unstable" seemingly doesnt work

    I started working on an alternate solution using fvm and melos. it's a bit wonky because i am installing fvm using the flutter 3.13.4 before getting it to install newer versions of flutter.

    Not being able to update the Flutter version is the only reason I don't use idx.

    Agreed. My project is currently on Flutter 3.16.3, can not run on 3.13.4 because of "TextScaler" error

    Still waiting on this, can't test this awesome IDE due to this issue not my apps running on older versions
