Help Testing Fix-It Hints In Existing Checker

Hey all,

I’m working on a change to add Fix-It Hints for missing _Nullable annotations (to automate annotating a large project) and I want to test the output. I spent today playing with LIT invocations (based on the existing nullability tests and other FixIts) but haven’t been able to get the output of the fixits to appear.

I have a WIP diff up at ⚙ D123352 [analyzer] Add FixItHint to `nullability.NullReturnedFromNonnull` and `nullability.NullableReturnedFromNonnull`.
