Following chapter 15 and converting the project to use moor is NOT WORKING

📚 Official Books Flutter Apprentice
1

I have tried to use the pubspec in the final project as suggesting in another post on the same issue, but it’s not helpful.

What’s wrong???

There’s no proofread process???

I think this book is going to damage the reputation of flutter since it’s on the official website of flutter.

Please provide correct solution regarding such issue and update the book.

Thank you!

[INFO] Precompiling build script... completed, took 7.2s

[SEVERE] Failed to precompile build script .dart_tool/build/entrypoint/build.dart.
This is likely caused by a misconfigured builder definition.

Other things I have tried:
flutter clean and re-install package, not working.

@seasonliii Thanks for raising this point.

It seems an issue similar to this Ch-15: Problem using moor_generator.
If that’s the case, the solution is Ch-15: Problem using moor_generator - #2 by dkdkdinesh000

The next version of the book (upcoming) includes a fix for this.
