update method

@override Future<Result<bool, String>> update()

Update or sync wallet transactions with blockchain. Return true if data changed. Is ignored if loadingTime is not zero.

Implementation

@override
Future<Result<bool, String>> update() async {
  if (_updateCalledTime != 0 && loadingTime < updateTimeout) {
    return Err('$walletName update already in progress');
  }
  _updateCalledTime = DateTime.now().millisecondsSinceEpoch;
  final result =
      await blockchainAdapter.updateWallet(stakeAddress: stakeAddress);
  if (result.isErr()) {
    _updateCalledTime = 0;
    return Err(result.unwrapErr());
  }
  bool changed = false;
  final update = result.unwrap();
  changed = refresh(
      balance: update.balance,
      transactions: update.transactions,
      usedAddresses: update.addresses,
      assets: update.assets,
      stakeAccounts: update.stakeAccounts);

  _updateCalledTime = 0; //reset timeout
  return Ok(changed);
}
