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"]);

完整代码的输出

I/flutter (24248): {sub: 1234567890, name: John Doe, admin: true, email: a@b.com, jti: b9d4b10f-78aa-4d37-894c-4462d0b6d50c, iat: 1583459979, exp: 1583463616}
