🎯 Component Examples

Using PrimaryButton

import { PrimaryButton } from './src/components';

<PrimaryButton
  title="Start Walk"
  onPress={() => navigate('NavigationMode')}
  loading={isLoading}
/>

Using SafeWalkMapView

import { SafeWalkMapView } from './src/components';

<SafeWalkMapView
  initialRegion={{
    latitude: 37.7749,
    longitude: -122.4194,
    latitudeDelta: 0.05,
    longitudeDelta: 0.05,
  }}
  markers={incidents}
  routePath={waypoints}
/>

Using Safety Score Calculator

import { calculateSafetyScore, getSafetyLevel } from './src/utils';

const score = calculateSafetyScore({
  incidentCount: 2,
  averageIncidentSeverity: 0.3,
  lightingQuality: 0.8,
  trafficVolume: 0.5,
  policePresence: 0.6,
  communityRating: 0.75,
});

const level = getSafetyLevel(score); // 'low', 'moderate', or 'high'
