React Native - Use fallback paywalls

Follow the instructions below to use the fallback paywalls in your mobile app code.

For Android

1. Place the fallback file you downloaded in the Adapty Dashboard to a directory on the native layer. There are 2 correct directories to put the file: android/app/src/main/assets/ or android/app/src/main/res/raw/.
   Please keep in mind that the res/raw folder has a special file naming convention (start with a letter, no capital letters, no special characters except for the underscore, and no spaces in the names).

   1. For android/app/src/main/assets/: Pass the file path relatively to the assets directory, for example:
      • { relativeAssetPath: 'android_fallback.json' } if you placed the file to the root of assets itself
      • { relativeAssetPath: '<additional_folder>/android_fallback.json' } if you placed it in a child folder of assets
   2. For android/app/src/main/res/raw/: Pass { rawResName: 'android_fallback' }. Type the file name without the file extension.

2. Pass the result of step 2 to the android property of FallbackPaywallsLocation.

For iOS

1. In XCode, use the menu File -> Add Files to "YourProjectName" to add the fallback file you downloaded in the Adapty Dashboard.
2. Pass { fileName: 'ios_fallback.json' } to the ios property of FallbackPaywallsLocation.

Here's an example of retrieving fallback paywall data from locally stored JSON files named android_fallback.json and ios_fallback.json.

//after v2.11
const paywallsLocation = {
  ios: {
    fileName: 'ios_fallback.json'
  },
  android: {
    //if the file is located in 'android/app/src/main/assets/'
    relativeAssetPath: 'android_fallback.json'
  }
}
await adapty.setFallbackPaywalls(paywallsLocation);

//Legacy (before v2.11)
const fallbackPaywalls = Platform.select({
  ios: require('./ios_fallback.json'),
  android: require('./android_fallback.json'),
});
// React Native automatically parses JSON, but we do not need that
const fallbackString = JSON.stringify(fallbackPaywalls);

await adapty.setFallbackPaywalls(fallbackString);
