No Identifiers allowed after numeric literals (React Native)

[AtmegaBuzz]

Describe the bug
When i added this line

        let wallet = walletSdk.Wallet.TestNet();

The react native was giving this error "No Identifiers allowed after numeric literals".
upon debugging i found our that it can due to the bignumber.js or big int used in the sdk

What version are you on?
"@stellar/typescript-wallet-sdk": "^1.5.0"

You should be sure to use a React Native compiler that supports BigInt literals (like 1234n).
