Class IapticTokensManager

Simple token balance manager that persists transactions to AsyncStorage.

Tracks all consumable token transactions and their corresponding amounts. When a transaction is added, it is appended to the persisted list. When a transaction is removed (refund), it is removed from the list. The balance is the sum of all amounts in the list.

Requires

@react-native-async-storage/async-storage — install with: npm install @react-native-async-storage/async-storage@~2.1.0
