1、flutter開發接入高德地圖包后運行報下面錯誤信息

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

運行在iPhone手機時出現以下錯誤信息：

=== 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.

解決方法：

進入flutter_project/ios/,編輯Podfile，將

# platform :ios, '9.0'

替換為：

platform :ios, '10.0'

use_frameworks!

關鍵是use_frameworks!

2、升級flutter后，高德地圖編譯失敗

報錯信息：

[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.

解決方法：在flutter的main里面添加下面一行代碼

WidgetsFlutterBinding.ensureInitialized();

這段代碼就行，代碼最高添加在main()函數的最上面，起碼要放在高德地圖初始化方法的前面
