" summary

Cash App says unidirectional UI works across 40+ engineers and 600+ modules: views in Kotlin or XML, presenters in Rx, Coroutines or Compose coexist via a binding that starts/stops presenters and converts different presenter types. Tests run on the JVM with paparazzi golden-image snapshots and CI verification, and presenters use molecule and turbine to expose flows; Broadway navigation wires view/presenter factories. The result is fast, testable screens and safe migrations.
