React Native Routes

Rotas de mapa (trajeto), não rotas de tela. Navegação de screens: react-native-expo-navigation. Directions HTTP: google-maps-apis. Desenho: google-maps-sdk.

Pipeline

origin + destination (+ waypoints)
  → Directions API (mode, alternatives)
  → pick route (default / user choice)
  → decode overview_polyline
  → <Polyline coordinates={...} />
  → fitToCoordinates(padding)
  → show ETA / distance
