QueryExecutor class Null safety

A query executor is responsible for executing statements on a database and return their results in a raw form.

This is an internal api of drift, which can break often. If you want to implement custom database backends, consider using the new backends API. The NativeDatabase implementation might be useful as a reference. If you want to write your own database engine to use with drift and run into issues, please consider creating an issue.
