A new Flutter project to showcase the parsing issue of big JSON-data between flutter 3.7.0 and flutter 3.7.1.

Install fvm

Documentation: https://fvm.app/docs/getting_started/installation/

macOS/Linux

brew tap leoafarias/fvm
brew install fvm

Windows

choco install fvm

Uninstall

macOS/Linux

brew uninstall fvm
brew untap leoafarias/fvm

Pub package

You are able to also install FVM as a pub package.

However if you plan on using FVM to manage your global Flutter install we recommend installing as a standalone.

dart pub global activate fvm

Switch Flutter Versions

Start out using v3.7.0 as this is the last one this Issue doesn't occur:

fvm use 3.7.0

If asked to install, confirm.

To switch versions, run:

fvm use 3.7.1

Note: when using VSCode, you may need to reload the window after this command for VSCode to recognize the change. Command Palette > Developer: Reload Window

Run the Flutter app

fvm flutter pub get # get packages
fvm flutter run # run the app

Reproduce the bug

1. Start out using Flutter version 3.7.0: fvm use 3.7.0
2. Get packages: fmv flutter pub get
3. Run the app: fmv flutter run (When using VSCode to run, be sure to reload the window)
4. The app should display "IHE XDS classCode by IHE Deutschland e.V."
5. Stop the app
6. Switch Flutter version to 3.7.1: fvm use 3.7.1
7. Get packages: fmv flutter pub get
8. Run the app: fmv flutter run (When using VSCode to run, be sure to reload the window)
