如何获取 Flutter 应用程序的构建和版本号 [英] How to get build and version number of Flutter app

问题描述

我目前正在开发一个目前处于测试模式的应用程序.因此，我想向他们展示他们使用的版本.例如，v1.0b10 - iOS".到目前为止，我得到了这个代码:Text("Build: V1.0b10 - " + (Platform.isIOS ? "iOS" : "Android")).我如何才能在 Flutter 中获得构建版本和编号?

I am currently developing an application which is currently in beta mode. Due to this, I would like to show them what version they are on. For example, "v1.0b10 - iOS". So far, I have got this code: Text("Build: V1.0b10 - " + (Platform.isIOS ? "iOS" : "Android")). How would I be able to get the build version and number within flutter?

推荐答案

您可以使用package_info_plus.

版本摘自:

安卓:

build.gradle, versionCode and versionName

iOS:

Info.plist, CFBundleVersion

用法

添加依赖

1. 将此添加到包的 pubspec.yaml 文件中:

dependencies:
  package_info_plus: ^1.0.6

1. 将文件导入您的 dart 文件:

import 'package:package_info_plus/package_info_plus.dart';

1. 如果您的方法被标记为async:

PackageInfo packageInfo = await PackageInfo.fromPlatform();

String appName = packageInfo.appName;
String packageName = packageInfo.packageName;
String version = packageInfo.version;
String buildNumber = packageInfo.buildNumber;

如果你不想使用await/async:

PackageInfo.fromPlatform().then((PackageInfo packageInfo) {
  String appName = packageInfo.appName;
  String packageName = packageInfo.packageName;
  String version = packageInfo.version;
  String buildNumber = packageInfo.buildNumber;
});
