Build: can not run build_runner in flutter v1.20.0

[Fjnova]

Hello team,

Thank you for making great Flutter framework.

I am trying app with Gitlab pipeline and have 1 issue with flutter v1.20.0 that I can not run this command

flutter pub run build_runner build

I got error message like:

Error: The getter 'externalKeyword' isn't defined for the class 'FieldDeclaration'.

I also try some ways like https://github.com/flutter/flutter/issues/62996 and https://github.com/flutter/flutter/issues/56779
But it sometime happens on my local environment, and always happens on gitlab pipepine

This is my yaml configuration file:
```image: cirrusci/flutter:1.20.0
stages:

• z
• t

before_script:

• flutter clean
• flutter pub get
• flutter pub run build_runner build

The problem is most likely due to the dependency override on analyzer, can you try removing that?

[sahmadreza]

I have the same problem ...

[sahmadreza]

I remove path: 1.7.0 from dependencies and use built_value: ^6.7.1 and works fine.

[NiklasEi]

I ran into the same issue, but could resolve it by removing the override on analyzer.

I ran into the same issue, but could resolve it by removing the override on analyzer.

This works for me too. You have to remove dependency_overrides: analyzer: 0.39.14 entirely.

[jakemac53]

Closing this as removing the analyzer appears to resolve things as expected
