Can't build because of missing nullable types

[miguelpruivo]

This is a major issue because I can't build and generated files always come up without nullable types support.

Hi @miguelpruivo,

The Flutter Intl extension checks the min version of the sdk under the pubspec.yaml file and generates localization code according to that value.

Could you check if updating the min sdk value solves your problem?

environment:
  sdk: ">=2.12.0 <3.0.0"

Hi @lzoran this is my environment:

environment:
  sdk: ">=2.13.0 <3.0.0"

It was working fine until today when intl updated and for some reason I start experiencing this issue.

Interesting...

I've tried your environment config, and everything works fine on my machine. 😕

The Flutter Intl extension relies on the globally activated intl_utils package. For Flutter projects that have min sdk constraint >=2.12.0, the extension should activate the intl_utils ^2.0.0.

Probably something went wrong after the update. Maybe deactivating the currently active intl_utils package and re-triggering the generation could help?

• flutter pub global deactivate intl_utils

• Update one of the arb files and save it (this should install the proper intl_utils version and trigger generation)

• Check if generated code is fixed Check if proper intl_utils is activated (flutter pub global list) Check if there are some errors under the Output > Flutter Intl window

In case this does not help, could you please provide us more details so we can try to reproduce this issue (VS Code version, Flutter Intl extension version, Flutter version)?

@lzoran just removed the generated folder and saved an .arb again and it fetched the right version, so it seems. Might have glitched during some update.

Thank you for your time.
