如何阻止此消息出现在终端中？

Question

选择 TextField() 且光标不断重新渲染时的终端输出

D/EGL_emulation( 4035): app_time_stats: avg=500.42ms min=487.06ms max=513.77ms count=2

问题是，当我在模拟器中打开 TextField 时，它会不断在终端中重复该烦人的消息。一旦我退出文本字段，它就会停止打印该错误。有人可以帮我吗？

class LoginPage extends StatefulWidget {



  @override

class _LoginPageState extends State<LoginPage> {

    Map<String, dynamic> parameters = {

    var url = Uri.http("192.168.1.14:3000", "users", parameters);
    var response = await http.get(url);

    dynamic fetchedData = jsonDecode(response.body);

    if(fetchedData['code'] == 404){
      print("-----------------404--------------------");
      return false;
    }

    print("Status code:  ${response.statusCode}");
    print(fetchedData['data']);

    return true;

                    ElevatedButton(onPressed: () {context.go('/login_and_register');}, child: Text("Back")),
                    SizedBox(width: 15),
                    ElevatedButton(onPressed: () async {
                      if(emailController.text.isEmpty || passwordController.text.isEmpty) {
                        return;
                      }

                      if(!(await checkIfUserIsCorrect(passwordController.text, emailController.text))){
                        return;
                      }

                      context.go('/');

                    child: Text("Submit"))
                  ],
                )
              ],
            ),
          ),
        ),
      ),
    );
  }
}

我想减少终端中的混乱程度并优化重新渲染问题。

如果您使用 Android Studio，请在终端中选择消息的开头，例如：

D/EGL_emulation(

然后右键单击并选择“像这样折叠线”。之后类似的消息将被折叠
