Installation

Let’s create a sample application together:

dart create demo

Now let’s add Polkadart packages, we will add all of them for demonstration purposes:

dart pub add polkadart polkadart_cli polkadart_keyring polkadart_scale_codec secp256k1_ecdsa sr25519 ss58 substrate_bip39 substrate_metadata

You should now have something like this in your pubsec.yaml file:

pubspec.yaml
