ChainSyncedBlock
Sync block data according to chain id.
import 'package:mystiko_flutter/mystiko_flutter.dart';
MystikoSynchronizerApi api = await Mystiko.mystikoSynchronizerApi();
Response<Int64, SynchronizerError> response = await api.chainSyncedBlock(1);
ContractSyncedBlock
Sync block data according to chain id and contract address.
import 'package:mystiko_flutter/mystiko_flutter.dart';
MystikoSynchronizerApi api = await Mystiko.mystikoSynchronizerApi();
Response<Int64, SynchronizerError> response = await api.contractSyncedBlock(1, '0x123456');
Status
Check the Sync Status.
Parameter: withContracts Indicates whether to include contract-related data in the synchronization status.
import 'package:mystiko_flutter/mystiko_flutter.dart';
MystikoSynchronizerApi api = await Mystiko.mystikoSynchronizerApi();
Response<SynchronizerStatus, SynchronizerError> response = await api.status(true);
Sync
Sync the data.
import 'package:mystiko_flutter/mystiko_flutter.dart';
MystikoSynchronizerApi api = await Mystiko.mystikoSynchronizerApi();
Response<void, SynchronizerError> response = await api.sync(SynchronizerSyncOptions());
