Summary: We will have several consumers for the measure infra soon (TextInput will use the same TextLayoutManager). It makes sense to move the cache there. In the future, iOS and Android implementations will probably use a bit different (platform-specific) cache implementations because we will implement the ability to measure "opaque"/platform-specific text containers alongside with normal AttributeStrings. Changelog: [Internal] Fabric-specific internal change. Reviewed By: mdvacca Differential Revision: D18445855 fbshipit-source-id: 7b7a65152ac13c74525da695612ae034904e82bf
