Decode Unsigned Transaction (Algorand Dart SDK)

AlgoSDK
1

Hi all!

Is there any way to decode unsigned transaction using Algorand Dart SDK? like JS-Algorand-SDK

Example using JS-Algorand-SDK :

const rawTx = algosdk.decodeUnsignedTransaction(base64ToByteArray(walletTx.txn))

You can do something like:

PaymentTransaction.fromJson(Encoder.decodeMessagePack(encodedBytes));

There’s no option (yet) for a generic Transaction object. Your best bet would be to decode the msgpack to a Map<String, dynamic> and then use a factory to parse the type to the correct tx.

Hii, if the data is like this, what transaction object should I use ? I have tried using ApplicationTransactionResponse.fromJson() but failed, because I need to sign the transaction. Thank You
