Currently ncu cannot detect update for the package:
https://www.npmjs.com/package/reanimated-bottom-sheet
Version string for this package looks like 1.0.0-alpha.X where X is bumped every release.
Thanks for reporting. This will be fixed with a breaking change in v4.
ncu v3 excludes prerelease versions from the remote by default, as publishing prerelease versions to latest is unconventional and in my opinion not recommended. Prereleases versions can be included by specifying --pre (and is implied in options --greatest and --newest).
However, when you are already specifying a prerelease version in your package.json dependencies, then clearly you want ncu to find newer prerelease versions. This will become default in v4, albeit with the conservative approach of sticking to the latest tag.
Published in v4.0.0
@raineorshine Unfortunately 4.0.0 don't fixed reported issue for me.
Currently if reanimated-bottom-sheet is sole outdated dependency ncu works as intended. But when there are more outdated dependencies (which are not in pre scope) reanimated-bottom-sheet is not being displayed on the list.

Using ncu --greatest or ncu --pre 1 yields correct results (both outdated dependencies are listed).
Good catch. That one made it past the unit test.
Try v4.0.1.
I can confirm that 4.0.1 fixed this issue, thank you!
