我有一个关于本机的应用程序.调试模式适用于ios.但发布模式不起作用.我尝试更改优化级别但没有帮助.我没有看到任何错误的问题.只是没有工作一些功能.我无法调试应用程序的发布版本.如何解决这个问题呢？

作为最后一个改变我们添加了以下saga,当我们删除调用这个传奇它工作

import { select, take, takeLatest, call, put, fork, race } from 'redux-saga/effects';
import R from 'ramda';
import V from 'o-validator';
import * as actionCreators from './actions';
import { redirectTo, showModalError, showModal, showOtp, closeOtp, errorOtp, loader, keychainSet } from '../../../actions/app-actions';
import { storeSession, refreshSession } from '../../../actions/session-actions';
import I18n from 'react-native-i18n';
import {
  KEYCHAIN_RESET,
  KEYCHAIN_GET,
  KEYCHAIN_RESULT
} from '../../../constants/action-types';


import { validatePassword, createCustomError, serverError } from '../../../services/utils';

const delay = (ms) => new Promise(resolve => setTimeout(resolve, ms)) …

我在 google play 控制台中收到以下错误，不知道如何解决。我不在我的应用程序中使用 SQLite。该错误在定位 SDK 30 后开始出现。将库升级到最新版本并没有帮助。

如何删除下拉底线？

我的代码

            Container(
              padding: EdgeInsets.fromLTRB(15, 5, 10, 5),
              child: Row(
                children: <Widget>[
                  dropdownButton,
                  Expanded(child: phoneField),
                ],
              ),
              decoration: BoxDecoration(
                  color: Colors.white,
                  border: Border.all(color: Colors.grey, width: 1),
                  borderRadius: BorderRadius.circular(32.0)),
            )

这是下拉

 var dropdownButton = DropdownButton(
      value: dropdownValue,
      onChanged: (String newValue) {
        setState(() {
          dropdownValue = newValue;
        });
      },
      items: <String>['99451', '99450', '99455', '99470 ']
          .map<DropdownMenuItem<String>>((String value) {
        return DropdownMenuItem<String>(
          value: value,
          child: Text(value),
        );
      }).toList(),
    );

我想创建以下自定义底部导航栏。如何为菜单项设置自定义布局？或者是否存在可以轻松创建这种类型的底部栏的现成库？

我有表HumanNames

输入是

|HumanName      |
|-------------  |
|Kamil          |
|Azer           |
|John           |
|Elmir          |
|Kamal          |
|Elmar          |
|Orxan          |
|Elnar          |

我需要写查询,它会给出与其他名称相同的结果名称.期望的输出是

|NamesWhichLikes  |
|-------------    |
|Kamil,Kamal      |
|Elmir,Elmar,Elnar|
|                 |

我有一个谷歌玩的应用程序超过5000000下载.和20000个每天+下载.当设计师将应用程序图标更改为新的好图标时,每日下载量从20000+ 减少到5000-.我不认为这不是好图标.我认为可能有一个营销策略后图标更改谷歌播放改变谷歌播放的应用程序位置.对此有何想法？
