文章未完成, 待续

因为java版本更新到21.0.5，打开flutter项目时vscode提示需求更新gradle版本

项目一些需要变更的位置

gradle-wrapper.properties

distributionBase=GRADLE_USER_HOME
distributionUrl=https\://services.gradle.org/distributions/gradle-8.9-bin.zip
distributionPath=wrapper/dists
zipStorePath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME

android/build.gradle两处变更

buildscript {
    ...略
    dependencies {
        classpath 'com.android.tools.build:gradle:8.7.0' // 对应gradle8.9版本
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
    ...略
}

   > Namespace not specified. Specify a namespace in the module's build file: C:\Users\alex\AppData\Local\Pub\Cache\hosted\pub.flutter-io.cn\uni_links-0.5.1\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. Refer to https://d.android.com/r/tools/upgrade-assistant/agp-upgrade-assistant for general information about using the AGP Upgrade Assistant.
