same value2 is ok，but why?

Hi @as1105

Map<String, dynamic> jsonMap = jsonDecode(value);

what is the value? are you sure you need to decode it, not data?

Hi @VladyslavBondarenko
Sorry,I found out that the problem is not the cause of jsonDecode.The original string was decrypted by calling Android's DES, I'm replacing all the arguments in there by replaceAll,
Log.d("解密后2-> ${value.toString().trim()}"); int a = value.length; Log.d("解密后2长度-> ${a.toString()}");
and I found out
I/flutter (26194): LOG v 解密后2-> I/flutter (26194): LOG v 解密后2长度-> 1
there was a mysterious character that didn't show up and could not be deleted through trim().
And then I went through
RegExp exp = new RegExp("\\{([^}]*)\\}"); value = "{" + exp.firstMatch(value).group(1) + "}";，
and the result goes through jsonDecode.
There may be some incompatibility between the dart characters and the Java characters.
Anyway, thanks!
