1：卡启动页的另外一个情况就是版本运行出错，用xcode运行真机会报错，卡启动页

具体情况如下

Runner[39545:15296040] [VERBOSE-2:dart_vm.cc(259)] VM snapshot must be valid.
Runner[39545:15296040] [VERBOSE-3:shell.cc(212)] Check failed: vm. Must be able to initialize the VM.

解决办法是https://github.com/flutter/flutter/issues/24641

修改Edit Scheme...为release

2：在pubspec.yaml中添加库文件导致的错误

D8: Program type already present: android.support.v4.os.ResultReceiver$MyResultReceiver

BUILD FAILED in 8s
*******************************************************************************************
The Gradle failure may have been because of AndroidX incompatibilities in this Flutter app.
See https://goo.gl/CP92wY for more information on the problem and how to fix it.
*******************************************************************************************
Finished with error: Gradle task assembleDebug failed with exit code 1

解决办法就是在这个文件里面添加如下代码

image.png

# 需要在gradle.properties中添加下面两行代码
# 这是因为混合支持库。通过添加这些行选择androidX作为您的支持库
android.useAndroidX=true
android.enableJetifier=true

3:个别页面出现无法进行debug断点调试，打了断点却无作用

///page
import 'package:flutter_employees_pms/Page/DashBoard//DashBoardPage.dart';

改成

///page
import 'package:flutter_employees_pms/Page/DashBoard/DashBoardPage.dart';

就因为这个页面在引用的时候多加了一个/

4：'multi_image_picker/multi_image_picker-Swift.h' file not found

Android没问题，但xcode中编译会报错，找了一圈

在这里填上这句话就好了，暂且不知道原理，应该是swift和OC混编问题

5:The iOS Simulator deployment target is set to x.x, but the range of supported deployment target versions for this platform is 8.0 to 12.0. (in target 'xxx')

post_install do |installer|
  installer.pods_project.targets.each do |target|
 target.build_configurations.each do |config|
  if config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'].to_f < 8.0
把Podfile里底下的代码替换成下面的

config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '8.0'
     end
   end
  end
end

6:warning: Could not find auto-linked framework 'Flutter'

修改xcode的Podfile

image.png

config.build_settings['ENABLE_BITCODE'] = 'NO'

注意放在target.build_configurations.each do |config|之下

7:Device doesn't support wireless sync. AMDeviceStartService(device, CFSTR("com.apple.debugserver"), &gdbfd, NULL)

flutter channel dev
/// 或下面
flutter channel master

老版本的bug，升级flutter就好了，但问题就是升级后会有很多改动休要手动修复
