Flutter 打包aab 并上传到google play生成签名的命令： keytool -genkey -v -ke

生成签名的命令：

keytool -genkey -v -keystore ./key.jks -keyalg RSA -keysize 2048 -validity 10000 -alias key

说明：keytool -export -alias 【密钥别名】-file 【导出路径】-keystore 【密钥文件路径】-storepass 【密码】

打包 apk 命令：

flutter build apk

指定架构 apk 打包命令：

flutter build apk --obfuscate --split-debug-info=debugInfo --target-platform android-arm,android-arm64,android-x64 --split-per-abi

打包完成后会在 build/app/outputs/apk/release下出现一个 app-release.apk 的文件。

打包bundle命令：

flutter build appbundle

打包完成后会在 build/app/outputs/bundle/release/app-release.aab出现一个aab 的文件，重命名后上传到google play 即可。

上传Google PLay

在通过命令行打包aab 上传googleplay 后出现了 您上传的是在调试模式下签名的 APK 或 Android App Bundle。请在发布模式下为 APK 或 Android App Bundle 签名的问题

所以后台改为了使用android studio进行打包

点击 create 便会在release 下生成好对应的aab 包，简单的重命名下就可以成功上传google play 了。

版本号修改

每次升级应用都会需要修改一下应用的版本号，那么如何操作呢？

（安卓原生项目）

（Flutter项目）

当然您也可以直接修改android 文件夹下的版本信息直接进行打包 文件路径：android/local.properties

sdk.dir=/Users/ymc/Library/Android/sdk
flutter.sdk=/usr/local/flutter
flutter.buildMode=release
flutter.versionName=1.0.2
flutter.versionCode=3

Flutter 项目中如果需要在项目中显示版本号，以GETX 示例：

binding.dart

import 'package:get/get.dart';

import 'controller.dart';

class AboutScreenBinding extends Bindings {
  @override
  void dependencies() {
    Get.lazyPut(() => AboutScreenController());
  }
}

controller.dart

import 'package:get/get.dart';
import 'package:package_info/package_info.dart';

import 'state.dart';

class AboutScreenController extends GetxController {
  final AboutScreenState state = AboutScreenState();

  @override
  void onReady() {
    super.onReady();
    getPackageInfo();
  }

  Future<Map<String, String>> getPackageInfo() async {
    PackageInfo packageInfo = await PackageInfo.fromPlatform();
    state.appName = packageInfo.appName;
    state.packageName = packageInfo.packageName;
    state.version = packageInfo.version;
    state.buildNumber = packageInfo.buildNumber;
    update(['about_version']);
    //Map<String, String> info = {};
    //info.addAll({ 'appName': packageInfo.appName });
    //info.addAll({ 'packageName': packageInfo.packageName });
    //info.addAll({ 'version': packageInfo.version });
    //info.addAll({ 'buildNumber': packageInfo.buildNumber });
    //return info;
  }

}

state.dart

class AboutScreenState {
  String version = '';
  String appName = '';
  String packageName = '';
  String buildNumber = '';
  AboutScreenState() {
    ///Initialize variables
  }
}
