build failed (flare_flutter/lib/flare.dart:1023) about developer_quest

Hello,

This error is due to a breaking change with Flutter master/dev. You are likely using one of those two channels. If you are trying to run the code in this repository, please use the Flutter stable branch by typing this into your terminal:

flutter channel stable
flutter upgrade

This is the easiest fix that should get you running very quickly. Alternatively, if you're adventurous, you can try to update the code to use a newer version of Flare (which is compatible with Flutter master/dev) by pointing the Flare-Flutter dependency to the dev branch in GitHub as follows:

flare_flutter:
  git: 
    url: git://github.com/2d-inc/Flare-Flutter.git
    ref: dev
    path: flare_flutter

We have details about how to do this in our Flare-Flutter readme here:
https://github.com/2d-inc/Flare-Flutter
