Flutter创建插件的命令

创建插件的命令flutter create --org com.plugin.demo --template=plugin --platforms=android,ios -i swift -a java plugin_demo

OC引用swift 文件

.m文件中添加以下代码//以下代码实现OC调用Swift
#if __has_include(<plugin_demo/plugin_demo-Swift.h>)#import <plugin_demo/plugin_demo-Swift.h>
#else// Support project import fallback if the generated compatibility header// is not copied when this plugin is created as a library.// https://forums.swift.org/t/swift-static-libraries-dont-copy-generated-objective-c-header/19816#import "plugin_demo-Swift.h"
#endif

IOS插件plugin_demo.podspec配置


当对.podspec文件进行修改后，需要对项目执行pod install才有效#
# To learn more about a Podspec see http://guides.cocoapods.org/syntax/podspec.html.
# Run `pod lib lint plugin_demo.podspec` to validate before publishing.
#
Pod::Spec.new do |s|s.name             = 'plugin_demo's.version          = '0.0.1's.summary          = 'A new Flutter plugin project.'s.description      = <<-DESC

以下配置来源于网上

   s.ios.source_files = 'PoCSDK/Classes/**/*','PoCSDK/Frameworks/Sinch.frameworks/Headers/*'#引用的第三方frameworks.ios.vendored_frameworks = 'PoCSDK/Sinch.framework'#配置头文件s.ios.public_header_files = 'PoCSDK/Frameworks/Sinch.frameworks/Headers/*'s.resource_bundles = {'NoddsSDK' => ['PoCSDK/Assets/*']}#指定项目中用到的系统库s.frameworks = 'UIKit', 'MapKit', 'AudioToolbox', 'AVFoundation's.ios.dependency 'Alamofire', '~> 4.5's.ios.dependency 'Socket.IO-Client-Swift's.ios.dependency 'ReachabilitySwift'

其它问题

当在.podspec文件中通过s.vendored_frameworks 配置了引用的第三方framework,但是build时依然编译不过
出现找不到对应的文件时，如 
iOS Undefined symbol: _OBJC_CLASS_$_XXXXXX ， _OBJC_CLASS_$_XXX", referenced from:        in XXX.o  
解决方法：
1.点击Pods 在TARGETS 找到对应的插件。
2.切换到General -> Frameworks and Libraries 中点击加号+选择。
3.选择在插件目录中用到的framework.
3.视情况看是否对Framework标记为 Embed & Sign
