getBlock()

Retrieving a blockchain block is not a transaction; it's simply a request executed by a single node. Sometimes, it might be necessary to send the same request multiple times to obtain the right copy

Method Signature

Future<dynamic> getBlock(String blockchain, int blockNumber);

Parameters

Name	Type	Description
blockchain	String	Blockchain address in hex
blockNumber	int	The number of the block you're looking for

Example

import 'package:circular_api/circular_api.dart';

void main() async{
    final circular = CircularAPI();
    final blockchain = "8a20baa40c45dc5055aeb26197c203e576ef389d9acb171bd62da11dc5ad72b2";
  
    final wallet = await circular.getBlock(blockchain, 1);
}

Result

The result will be an object of type Map<String, dynamic>
