Unknown column type does not crash build

[JamesMcIntosh]

When generating a column which is an unknown data type an error should be thrown.

When you run flutter pub run build_runner build it says that it succeeds with 1 less actions than expected. All that is shown in the console is a warning in the logs which doesn't indicate that anything went wrong.

[INFO] Running build...
[WARNING] jaguar_orm_gen:jaguar_orm_gen on lib/test/NullableClass.dart:
Generating bean for NullableClass ...
[INFO] Running build completed, took 2.2s

[INFO] Caching finalized dependency graph...
[INFO] Caching finalized dependency graph completed, took 47ms

[INFO] Succeeded after 2.2s with 1 outputs (1 actions)

The error is written as a comment into the jorm.dart file with a stack trace.

class NullableClass extends Equatable {
  @Column(isNullable: true)
  Optional<String> nullableValue;

  NullableClass({this.nullableValue}) : super([nullableValue]);

}
