Getting coins from the faucet

Faucet V0

final faucet = FaucetClient(SuiUrls.faucetDev);
await faucet.requestSuiFromFaucetV0('0xa2d8bb82df40770ac5bc8628d8070b041a13386fef17db27b32f3b0f316ae5a2');

Sui Account

Create account with private key

/// Ed25519 account
final ed25519 = SuiAccount.ed25519Account();
final ed25519Import = SuiAccount.fromPrivateKey(ed25519.privateKey());

/// Secp256k1 account
final secp256k1 = SuiAccount.secp256k1Account();
final sepc256k1Import = SuiAccount.fromPrivateKey(secp256k1.privateKey());

/// Secp256r1 account
final secp256r1 = SuiAccount.secp256r1Account();
final sepc256r1Import = SuiAccount.fromPrivateKey(secp256r1.privateKey());

Create account with mnemonic

/// create mnemonics
final mnemonics = SuiAccount.generateMnemonic();

/// Ed25519 account
final ed25519 = SuiAccount.fromMnemonics(mnemonics, SignatureScheme.Ed25519);

/// Secp256k1 account
final secp256k1 = SuiAccount.fromMnemonics(mnemonics, SignatureScheme.Secp256k1);

/// Secp256r1 account
final secp256r1 = SuiAccount.fromMnemonics(mnemonics, SignatureScheme.Secp256r1);

Writing APIs

Transfer Object

final account = SuiAccount.fromMnemonics(mnemonics, SignatureScheme.Ed25519);
final client = SuiClient(SuiUrls.devnet);

final tx = Transaction();
tx.transferObjects(
    [tx.objectId('0x2619f581cb1864d07c89453a69611202669fdc4784fb59b9cb4278ec60756011')], 
    account.getAddress()
);

final result = await client.signAndExecuteTransactionBlock(account, tx);
print(result.digest);

Split and Transfer Coins

final account = SuiAccount.fromMnemonics(mnemonics, SignatureScheme.Ed25519);
final client = SuiClient(SuiUrls.devnet);

final tx = Transaction();
final coin = tx.splitCoins(tx.gas, [1000]);
tx.transferObjects(
    [coin],
    account.getAddress()
);

final result = await client.signAndExecuteTransactionBlock(account, tx);
print(result.digest);

Merge Coins

final account = SuiAccount.fromMnemonics(mnemonics, SignatureScheme.Ed25519);
final client = SuiClient(SuiUrls.devnet);

final tx = Transaction();
tx.mergeCoins(tx.objectId('0x922ec73939b3288f6da39ebefb0cb88c6c54817441254d448bd2491ac4dd0cbd'), 
    [tx.objectId('0x8dafc96dec7f8d635e052a6da9a4153e37bc4d59ed44c45006e4e9d17d07f80d')]
);

final result = await client.signAndExecuteTransactionBlock(account, tx);
print(result.digest);

Move Call

final account = SuiAccount.fromMnemonics(mnemonics, SignatureScheme.Ed25519);
final client = SuiClient(SuiUrls.devnet);

const packageObjectId = '0x...';
final tx = Transaction();
tx.moveCall('$packageObjectId::nft::mint', arguments: [tx.pureString('Example NFT')]);

final result = await client.signAndExecuteTransactionBlock(account, tx);
print(result.digest);

Publish Modules

final account = SuiAccount.fromMnemonics(mnemonics, SignatureScheme.Ed25519);
final client = SuiClient(SuiUrls.devnet);

const moduels = <String>[];
const dependencies = <String>[];
final tx = Transaction();
final upgradeCap = tx.publish(moduels, dependencies);
tx.transferObjects([upgradeCap], account.getAddress());

final result = await client.signAndExecuteTransactionBlock(account, tx);
