Call read-only method

starknet_getBlockWithReceipts: Retrieves block information with transaction receipts. Returns BlockWithReceipts with optional fields. Note: Devnet may return null fields for invalid block IDs instead of throwing BLOCK_NOT_FOUND.

starknet_getTransactionStatus

Get the transaction status (whether it was received, rejected, accepted on L2, or accepted on L1).

Future<TransactionStatus> getTransactionStatus(Felt transactionHash);

Example:

final status = await provider.getTransactionStatus(transactionHash);
print('Transaction status: ${status.finalityStatus}');
print('Execution status: ${status.executionStatus}');

The TransactionStatus model includes:

finalityStatus: The finality status of the transaction (RECEIVED, REJECTED, ACCEPTED_ON_L2, ACCEPTED_ON_L1)
executionStatus: The execution status of the transaction (SUCCEEDED, REVERTED)
