ConstraintLayout 2.0

" summary

ConstraintLayout 2.0 shows concrete additions: barriers and optimizer reduce solver calls and cut remeasures, a new dimension optimizer aims to avoid multiple text measures, and tooling hooks land in Android Studio 3.2. It ships helper primitives that actually work — layer and decorator helpers for grouped transforms and reveals, virtual layouts like flow/linear for flat chains, and a state.xml and ConstraintSet API for switching layouts without reinflation.
