Get asset code from offers

[AliKarimiENT]

Hello I have faced an issue: I can not get Selling and Buying asset's code from offers of an account. For example, I have created an offer from native to BTC. When I load the offers, there is no property to get the asset's code. Please check this Thanks

This actually is in Asset class that there is nothing to get asset code

Well I don't know flutter so take everthing with a grain of salt but you won't find that field in the Asset base class as ... not all assets have a code. XLM/native is also an asset, but none with an issuer or code. So you'll need to test if the asset is an ALPANUMARIC asset and 🎉 you'll find the code and issuer properties. https://github.com/Soneso/stellar_flutter_sdk/blob/61f48613baf5baf904999f548adcff1e72b35184/lib/src/asset_type_credit_alphanum.dart#L11-L12

Thanks, I defined these variables late stl.AssetTypeCreditAlphaNum sellingAsset,buyingAsset; And initialized with a cast to AssetTypeCreditAlphaNum sellingAsset = offer.selling as stl.AssetTypeCreditAlphaNum;
