Flutter 3.29+使用isar构建失败
执行命令：flutter build apk --release
报错
Flutter assets will be downloaded from https://storage.flutter-io.cn. Make sure you trust this source!FAILURE: Build failed with an exception. * What went wrong:
A problem occurred configuring project ':isar_flutter_libs'.
> Could not create an instance of type com.android.build.api.variant.impl.LibraryVariantBuilderImpl. > Namespace not specified. Specify a namespace in the module's build file: C:\Users\17602\AppData\Local\Pub\Cache\hosted\pub.flutter-io.cn\isar_flutter_libs-3.1.0+1\android\build.gradle. See https://d.android.com/r/tools/upgrade-assistant/set-namespace for information about setting the namespace.If you've specified the package attribute in the source AndroidManifest.xml, you can use the AGP Upgrade Assistant to migrate to the namespace value in the build file.

- 然后参考：https://github.com/isar/isar/issues/1672
在\android\build.gradle.kts文件中添加以下代码
// 添加这部分代码，且当前subprojects 必须是当前文件的第一个subprojects块
subprojects {afterEvaluate {project.extensions.configure<com.android.build.gradle.BaseExtension> {if (namespace == null) namespace = project.group.toString()}}
}
再次尝试构建，发现会提示另一个错误：
FAILURE: Build failed with an exception.What went wrong:
Execution failed for task ':isar_flutter_libs:verifyReleaseResources'.
A failure occurred while executing com.android.build.gradle.tasks.VerifyLibraryResourcesTask$Action

- 最后再另一个issue里面找到了解决方案：
https://github.com/isar/isar/issues/1681
使用以下subprojects 区块代码，替换\android\build.gradle.kts里的所有subprojects 区块
subprojects {val newSubprojectBuildDir: Directory = newBuildDir.dir(project.name)project.layout.buildDirectory.value(newSubprojectBuildDir)
}subprojects {afterEvaluate {if (project.hasProperty("android")) {val androidExtension = project.extensions.findByName("android")if (androidExtension is com.android.build.gradle.BaseExtension) {androidExtension.compileSdkVersion = "android-35"androidExtension.buildToolsVersion = "35.0.0"androidExtension.ndkVersion = "27.0.12077973"if (androidExtension.namespace == null) {androidExtension.namespace = project.group.toString()}}}}
}subprojects {project.evaluationDependsOn(":app")
}
最后再执行构建命令就可以成功构建了
但是后来发现isar在github上已经两年多没更新了，遂切换其他本地数据库
