React

isSolanaGasSponsorshipEnabled is synchronous and works the same in React. Use it inside a button handler to decide which send function to call: 
import { isSolanaGasSponsorshipEnabled } from '@dynamic-labs-sdk/solana';
import { signAndSendSponsoredTransaction, signAndSendTransaction, isSolanaWalletAccount } from '@dynamic-labs-sdk/solana';
import { useWalletAccounts } from '@dynamic-labs-sdk/react-hooks';

function SendButton({ transaction }) {
  const walletAccounts = useWalletAccounts();
  const walletAccount = walletAccounts.find(isSolanaWalletAccount);

  const handleSend = async () => {
    if (!walletAccount) return;

    if (isSolanaGasSponsorshipEnabled()) {
      await signAndSendSponsoredTransaction({ transaction, walletAccount });
    } else {
      await signAndSendTransaction({ transaction, walletAccount });
    }
  };

  return (
    <button onClick={handleSend} disabled={!walletAccount}>
      Send {isSolanaGasSponsorshipEnabled() ? '(Sponsored)' : ''}
    </button>
  );
}
