/* * With prepared text layout, Fabric keeps the android.text.Layout it builds * while measuring text and PreparedLayoutTextView draws it as-is, instead of * ReactTextView (an AppCompatTextView) building a second layout on the UI * thread. * * The override must run after loadReactNative() installs the release-level * flags and before any ReactHost or Activity reads a flag. It replaces the * whole flag provider, so it is only applied on the STABLE release level, whose * provider is an empty subclass of ReactNativeNewArchitectureFeatureFlagsDefaults. * * Prepared layouts bypass Fabric's regular text measurement cache, so the * prepared text cache is the only one left. Its default of 200 entries is * smaller than the number of text nodes in a long thread or feed, which makes * scrolling re-measure text on the JS thread. */const override = ` if (DefaultNewArchitectureEntryPoint.releaseLevel == ReleaseLevel.STABLE) { val flagsReadEarly = ReactNativeFeatureFlags.dangerouslyForceOverride( object : ReactNativeNewArchitectureFeatureFlagsDefaults() { override fun enablePreparedTextLayout() = true override fun preparedTextCacheSize() = 1000.0 }) if (flagsReadEarly != null) { Log.w("MainApplication", "Feature flags read before override: $flagsReadEarly") } }`
