Shoot, I enable null safety checks, work those issues, only to find out that undefined safety checks are far more common and harder to fix.

```json
{
"strictNullChecks": true,
"strictPropertyInitialization": true,
}
````

On a pre-existing code base, setting "neutral" default values is the way to go. In greenfield code, meaningful constructors, maybe.
