Git dependencies issue

[voltaire-lre]

Not sure if this is an issue with the vscode extension of with flutterflow

I added a custom git dependency in the pubspec file.
I used the format :
my_package:
git:
url: https://user:token@github.com/my_package

Once I pushed and the pull from flutterflow the dependency is changed to my_pckage: {git: {url: ....}}
This is OK but in flutterflow I got an error :

To avoid the issue in flutterflow I need to remove the brackets to set git: {url: ...} instead of {git: {url: {....}}
However when I do that, the next pull will remove the git line from the pubspec in vscode.
