【中文标题】Flutter 构建在 iOS 上失败，但在 android 上工作【英文标题】：Flutter build failed on iOS but works on android 【发布时间】：2019-10-08 04:35:43 【问题描述】：在 ios 上构建和运行 Flutter 应用程序失败。它在 android 上工作，但在 iOS 上中断并失败
我正在使用 iphone 8 模拟器。
flutter --version Flutter 1.3.8 • 频道测试版 • https://github.com/flutter/flutter.git 框架 • 修订版 e5b1ed7a7f （3 个月前）• 2019-03-06 14:23:37 -0800 引擎• 修订 f4951df193 工具 • Dart 2.2.1（构建 2.2.1-dev.0.0 571ea80e11）
发布规范 名称：icps 描述：一个新的 Flutter 项目。
# The following defines the version and build number for your application.
# A version number is three numbers separated by dots, like 1.2.43
# followed by an optional build number separated by a +.
# Both the version and the builder number may be overridden in flutter
# build by specifying --build-name and --build-number, respectively.

【问题讨论】：
您的部署目标/支持的最低 iOS 版本是多少？ 部署目标是iOS 8 5个月后，你解决了吗？我有同样的问题，但我得到的错误是：[！] 无法找到FMDB (~> 2.7.2) 的规范，这取决于 sqflite
【参考方案1】：
选项 1： 在Podfile中，将target增加到9并删除Podfile.lock并运行（flutter build IOS）
选项 2： 如果不起作用，请尝试更改 Podfile：
target 'Runner' do
# Flutter Pod
use_frameworks!
use_modular_headers!
然后： 扑干净 删除 Podfile.lock 吊舱安装--repo-update pod 更新 FBSDKLoginKit
打开 .xcworkspace 并在 General-> Deployment Info 中设置 Target 11.0 也在 Podfile 中设置 Target 11.0
【讨论】：
以上是关于Flutter 构建在 iOS 上失败，但在 android 上工作的主要内容，如果未能解决你的问题，请参考以下文章
