// Pass the node's RPC endpoint
final client = CasperClient(Uri.parse("http://127.0.0.1:7777/rpc"));

client.getPeers().then((result) {
  for (final peer in result.peers) {
    print(peer.address);
  }

Development

Building

Get dependencies:

dart pub get

To auto-generate serialization-deserialization classes, run build runner:

dart run build_runner build

Testing

Run all tests:

dart test

Run specific test file:

dart test test/utils_test.dart

Test Environment

The environment variable CASPER_TEST_NODE_RPC_URL must be set to run the tests. Bare in mind that currently, some of the tests might be specific to the test node http://138.201.54.44:7777/rpc. The server responses should be mocked instead of relying on a single test node.
