百度平台部分
设置 AK

- 添加应用
- 查看 Bundle Identifier
IOS 部分
自动部署 CocoaPods
- 安装工具
sudo gem install cocoapods- ios/flutter_baidu_plugin_ducafecat.podspec
...
s.dependency 'Flutter'
s.platform = :ios, '8.0'
s.dependency 'BMKLocationKit'
# Flutter.framework does not contain a i386 slice. Only x86_64 simulators are supported.
s.pod_target_xcconfig = { 'DEFINES_MODULE' => 'YES', 'VALID_ARCHS[sdk=iphonesimulator*]' => 'x86_64' }
end- 安装百度 sdk 包
pod install- 升级
pod repo update- pod search 无法搜索到类库的解决办法（找不到类库）
（1）执行pod setup
（2）删除~/Library/Caches/CocoaPods目录下的search_index.json文件
pod setup成功后会生成~/Library/Caches/CocoaPods/search_index.json文件
终端输入rm ~/Library/Caches/CocoaPods/search_index.json
删除成功后再执行pod search
（3）执行pod searchInfo.plist 定位授权
