随着flutter技术的发展,越来越多的开发者开始选择用Flutter开发一些功能,基于现有的项目,通常有两种方式引入Flutter:
1、为项目创建一个flutter module,通过library方式引入flutter功能。
2、创建一个独立的flutter app,改造成module,然后将module打包成aar让主工程引用。
第一种方式是官方推荐的引用方式,通过官方文档 Add-Flutter-to-existing-apps 即可了解,这里主要讲解第二种形式。
第二种方式首先需要搭建maven远程仓库,这里就先假设已经搭建好了maven仓库。下面首先需要创建一个Flutter App工程并修改为module。
1、创建Flutter Application
2、修改打包方式为library
3、上传aar到maven仓库
uploadArchives {
configuration = configurations.archives
repositories {
mavenDeployer {
android.libraryVariants.all { variant ->
def _flavorBuildTypeName = "release"
addFilter(_flavorBuildTypeName) { artifact, file ->
true
}
repository(url: "maven仓库地址") {
authentication(userName: maven上传用户名, password: maven上传密码)
}
pom(_flavorBuildTypeName).groupId = "xxx"
pom(_flavorBuildTypeName).artifactId = "xxx"
pom(_flavorBuildTypeName).version = "xxx"
pom(_flavorBuildTypeName).name = 'xxx'
pom(_flavorBuildTypeName).packaging = 'aar'
pom(_flavorBuildTypeName).withXml {
def root = asNode()
def depsNode = root["dependencies"][0] ?: root.appendNode("dependencies")
def addDep = {
if (it.group == null) return // Avoid empty dependency nodes
def dependencyNode = depsNode.appendNode('dependency')
dependencyNode.appendNode('groupId', it.group)
dependencyNode.appendNode('artifactId', it.name)
dependencyNode.appendNode('version', it.version)
if (it.hasProperty('optional') && it.optional) {
dependencyNode.appendNode('optional', 'true')
}
//生成依赖包的mvn 部署
def dir = file('../../build/')
def repoUrl = "maven仓库地址"
dir.eachFileRecurse { file ->
if (file.name.contains(it.name) && file.name.endsWith("-release.aar")) {
def command = "cmd /k mvn deploy:deploy-file"
.concat(" -DgroupId=${it.group}")
.concat(" -DartifactId=${it.name}")
.concat(" -Dversion=${it.version}")
.concat(" -Dpackaging=aar")
.concat(" -Dfile=${file.path}")
.concat(" -Durl=${repoUrl}")
.concat(" -DgeneratePom=true")
//将该flutter module依赖的其余的library上传到maven
Process p = Runtime.getRuntime().exec(command)
}
}
}
configurations.api.allDependencies.each addDep
configurations.implementation.allDependencies.each addDep
}
}
}
}
4、第3步中mvn deploy需要在本地安装maven并配置用户名密码
4.1、安装maven
4.2、配置用户名密码
<server>
<id>remote-repository</id>
<username>xxx</username>
<password>xxx</password>
</server>
5、设置Flutter SDK的目录
进入android文件夹下设置local.properties
设置flutter.sdk=xxx 为当前机器本地的flutter目录
6、拷贝icudatl.dat到对应目录
7、拷贝 ${flutter_sdk}/packages/flutter_tools/templates/module/android/library/Flutter.tmpl/src/main/java/io/flutter/facade到目录
8、windows下dos窗口执行 gradle clean uploadArchives --info(当然要在mac下运行,修改build.gradle脚本,不会的可以评论区留言)
9、最后,可以在主工程中依赖该aar
iOS9上面启动crash问题备忘:发布iOS版本后,发现iOS9在启动时crash。crash log如下:
经排查,发现是缺失 libSystem.B.dylib 导致,需要手动加入:
couldn't find "libflutter.so"怎么办?
