A Future-based library to interact with the Li.Fi API.
This package is a wrapper around the Li.Fi API, allowing easy swapping of tokens between blockchain networks with Dart. It is multi-platform, with limited dependencies for use in mobile, desktop, or browser apps.
This community package is designed to follow the Li.Fi API Documentation as closely as possible.
Using
The easiest way to use this library is via the top-level Lifi
class.
import 'package:lifi_api_dart/lifi_api_dart.dart';
void main() async {
/// Set up the config
Config config = Config(
environment: Constants.production, // mainnets
// environment: Constants.staging, // testnets
apiVersion: Constants.v1,
);
/// Initialize the main object
Lifi lifi = Lifi(config);
/// Prepare options for the quote
GetQuoteParams getQuoteParams = GetQuoteParams(
fromChain: 'ETH',
toChain: 'POL',
fromToken: 'USDC',
toToken: 'ETH',
fromAddress: '0x_sender_address',
fromAmount: '100000000',
);
/// Get a quote
///
/// The response contains a Transaction that can be signed and sent
/// to the network using a wallet provider. eg. Ethers
var response = await lifi.getQuote(getQuoteParams);
/// Close the connection
lifi.close();
}
Testing your integration
Testnet support is limited and not reflective of the production environment. If possible, try to use LI.FI on a mainnet with low gas fees instead.
Switch between staging (testnet) and production by changing the environment
value
in the config.
/// Set up the config
Config config = Config(
environment: Constants.production, // mainnet
// environment: Constants.staging, // testnets
apiVersion: Constants.v1,
);
Advanced endpoints
Although advanced endpoints such as getPossibilities
, getRoutes
, and
getStepTransaction
are not recommended to be used directly, they are included
in this library for completeness.
