Flutter接入高德地图后运行报错

1、flutter开发接入高德地图包后运行报下面错误信息

fatal error: 'simple_permissions/simple_permissions-Swift.h' file not found

运行在iPhone手机时出现以下错误信息：

=== BUILD TARGET url_launcher OF PROJECT Pods WITH CONFIGURATION Debug ===

/Users/bobo/flutter/flutter/.pub-cache/hosted/pub.dartlang.org/simple_permissions-0.1.9/ios/Classes/SimplePermissionsPlugin.m:2:9: fatal error: 'simple_permissions/simple_permissions-Swift.h' file not found

#import 

       ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

1 error generated.

解决方法：

进入flutter_project/ios/,编辑Podfile，将

# platform :ios, '9.0'

替换为：

platform :ios, '10.0'
use_frameworks!

关键是use_frameworks!

2、升级flutter后，高德地图编译失败

报错信息：

[VERBOSE-2:ui_dart_state.cc(148)] Unhandled Exception: ServicesBinding.defaultBinaryMessenger was accessed before the binding was initialized.
If you're running an application and need to access the binary messenger before `runApp()` has been called (for example, during plugin initialization), then you need to explicitly call the `WidgetsFlutterBinding.ensureInitialized()` first.
If you're running a test, you can call the `TestWidgetsFlutterBinding.ensureInitialized()` as the first line in your test's `main()` method to initialize the binding.

解决方法：在flutter的main里面添加下面一行代码

WidgetsFlutterBinding.ensureInitialized();

这段代码就行，代码最高添加在main()函数的最上面，起码要放在高德地图初始化方法的前面
