[Crash Report] LOADING Icon causes crash on ios.

• Flutter: 1.61.1
• iOS: 13.3

I think this may be the compatibility problem, when we use flutter 1.15 on ios, it works fine, and flutter 1.16 on Android works fine, and others icon works fine too.

Appeared on Flutter new version 1.17.
Will this be fixed? Really want to use it.
