您可以在下面复制粘贴运行完整代码
您可以使用包https://pub.dev/packages/jwt_decode来解析 JWT 令牌

代码片段

import 'package:jwt_decode/jwt_decode.dart';

var token = 'eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiYWRtaW4iOnRydWUsImVtYWlsIjoiYUBiLmNvbSIsImp0aSI6ImI5ZDRiMTBmLTc4YWEtNGQzNy04OTRjLTQ0NjJkMGI2ZDUwYyIsImlhdCI6MTU4MzQ1OTk3OSwiZXhwIjoxNTgzNDYzNjE2fQ.D5cMT_nMLcTlZLgW7DbGs_cxZ8mpyOsAzI68JFPpboA';
var payload = Jwt.parseJwt(token);
print(payload);
print(payload["email"]);
