Avoid iOS text selection crash by returning nil range #161996

importRyan · 2025-01-22T08:35:35Z

Previously approved in /engine before monorepo shift.

Reverts an unnecessary assertion introduced by #16496 that crashes upon valid user text field interactions. Follow-on work can resolve the underlying discrepancy between iOS and Flutter range finding (see #160100). For crash reports, see issue #138464.

@cbracken @hellohuanlin @LongCatIsLooong @jmagman On vacation, but caught that the engine PR fell out due to monorepo migration. This re-ups that. (In tidying up the links w/ monorepo, noticed that we're coming up to the 5 year anniversary of this NSAssert!)

Re-LGTM. As mentioned, we had already lgtm'ed the old engine PR. Once we've got the second LGTM, we'll tag it with autosubmit and land. Thanks again.

May I land this?

May I land this?

Yes! I just put an autosubmit
