moor build_runner does not create generated file - flutter

Question

I have the latest flutter & dart. I create a basic app and then use the getting started code from the moor website: https://moor.simonbinder.eu/docs/getting-started/
When I execute the build runner it runs but exits with no error message in the moor build but no moor_test.g.dart file is created.
Here is the verbose output from build runner:

Here is my pubspec.yaml file:
name: moor_test
description: A new Flutter project.
publish_to: 'none' # Remove this line if you wish to publish to pub.dev
version: 1.0.0+1
environment:
sdk: ">=2.7.0 <3.0.0"
dependencies:
flutter:
sdk: flutter
moor: # use the latest version
sqlite3_flutter_libs: # Also use the latest version.
path_provider:
path:
cupertino_icons: ^1.0.2
dev_dependencies:
flutter_test:
sdk: flutter
moor_generator: # use the latest version
build_runner:
flutter:
uses-material-design: true
And my moor class:
import 'package:moor/moor.dart';
part 'moor_test.g.dart';
class Todos extends Table {
IntColumn get id => integer().autoIncrement()();
TextColumn get title => text().withLength(min: 6, max: 32)();
TextColumn get content => text().named('body')();
IntColumn get category => integer().nullable()();
}
#DataClassName("Category")
class Categories extends Table {
IntColumn get id => integer().autoIncrement()();
TextColumn get description => text()();
}
#UseMoor(tables: [Todos, Categories])
class MyDatabase {
}
Does anyone know what I am doing wrong or can prompt me where to look to debug this?
