Flutter build and version number

问题：

Flutter 如何获取App 的 build 和 version 版本号？

解决方法：

Android:

build.gradle, versionCode and versionName

iOS:

Info.plist, CFBundleVersion

Add the dependency

添加依赖到 pubspec.yaml file:

dependencies:
  package_info: ^0.4.0+16

导入头文件

import 'package:package_info/package_info.dart';

异步调用async:

PackageInfo packageInfo = await PackageInfo.fromPlatform();

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

同步调用 await/async:

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