How to get build and version number of Flutter app

Question

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?

Answer 1

You can use package_info_plus.

The versions are extracted from:

Android:

build.gradle, versionCode and versionName

iOS:

Info.plist, CFBundleVersion

Usage

Add the dependency

1. Add this to your package's pubspec.yaml file:

dependencies:
  package_info_plus: ^1.0.6

2. Import the file into your dart file:

import 'package:package_info_plus/package_info_plus.dart';

3. if your method is marked as async:

PackageInfo packageInfo = await PackageInfo.fromPlatform();

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

If you don't want to use await/async:

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

Note: This answer has been updated to reflect the fact that the package_info plugin is deprecated and redirects to package_info_plus.

Version name and build number

At development time, you can easily find the version name and build number of a Flutter or Dart project by inspecting pubspec.yaml. Here is an example:

version: 1.1.0+2

This is case the version name is 1.1.0 and the build number is 2.

However, if you want to get these values at runtime, you should use a plugin.

Add the dependency

In pubspec.yaml add the package_info_plus package.

dependencies:
  package_info_plus: ^1.0.2

Update the version number to the current one.

Import the package

In the file that you need it, add the following import.

import 'package:package_info_plus/package_info_plus.dart';

Get the version name and code

In your code you can get the app version name and code like this:

PackageInfo packageInfo = await PackageInfo.fromPlatform();
String version = packageInfo.version;
String code = packageInfo.buildNumber;

install package_info_plus, then you can use it directly with future builder in your widget tree:

 FutureBuilder<PackageInfo>(
              future: PackageInfo.fromPlatform(),
              builder: (context, snapshot) {
                switch (snapshot.connectionState) {
                  case ConnectionState.done:
                    return Align(
                      alignment: Alignment.bottomCenter,
                      child: Text(
                        'Version: ${snapshot.data!.version}',),
                      );
                  default:
                    return const SizedBox();
                }
              },
            ),

Answer 4

RE the multiple references to package_info, please note that this package has been deprecated and the recommended replacement is the Flutter Community Plus Plugins version, package_info_plus.

Answer 5

You can try new_version plugin. Using this plugin you can get installed App Version, Playstore App Version and app url which can redirect to playstore.

New Version Plugin

void versionCheck() async {
    final NewVersion newVersion = NewVersion(context: context);
    VersionStatus versionStatus = await newVersion.getVersionStatus();
    if (versionStatus != null && versionStatus.canUpdate) {
      await ConfirmDialog(
          context: context,
          title: 'Update Available',
          body: Text('A new version, ${versionStatus.storeVersion}, is available.'),
          acceptButton: 'Update Now',
          cancelButton: 'Update Later'
      ).then((ConfirmAction res) async {
        if (res == ConfirmAction.CONFIRM && await canLaunch(versionStatus.appStoreLink)) {
          await launch(versionStatus.appStoreLink, forceWebView: false);
        }
      });
    }
  }

Custom Alert Dialog Box

enum ConfirmAction{ CONFIRM, CANCEL }
Future<ConfirmAction> ConfirmDialog({
  BuildContext context,
  String title,
  Widget body,
  String acceptButton,
  String cancelButton
})
=> showDialog(
    context: context,
    barrierDismissible: false,
    builder: (BuildContext context) => AlertDialog(
      title: Wrap(
        crossAxisAlignment: WrapCrossAlignment.center,
        spacing: 4,
        children: <Widget>[
          Text(title)
        ],
      ),
      content: Wrap(
        runSpacing: 10,
        children: <Widget>[
          body,
        ],
      ),
      actions: <Widget>[
        FlatButton(
            padding: EdgeInsets.all(6),
            child: Text(acceptButton ?? 'Confirm'),
            onPressed: (){
              Navigator.of(context, rootNavigator: true).pop(ConfirmAction.CONFIRM);
            }
        ),
        FlatButton(
            padding: EdgeInsets.all(6),
            child: Text(cancelButton ?? 'Cancel'),
            onPressed: (){
              Navigator.of(context, rootNavigator: true).pop(ConfirmAction.CANCEL);
            }
        ),
      ],
    )
);

Answer 6

For using it from command line or CLI, you need a pure Dart code.

I used the following script:

// ignore_for_file: avoid_print
import 'dart:io';

import 'package:path/path.dart';
import 'package:yaml/yaml.dart';

String pathToYaml = join(dirname(Platform.script.toFilePath()), '../pubspec.yaml');

Future<YamlMap> loadPubspec() async => loadYaml(await File(pathToYaml).readAsString());

void main() async {
  var pubspec = await loadPubspec();
  print(pubspec['version'].toString().split('+')[0]);
}

You can run it from the project root folder:

dart run scripts/get_version_name.dart

Answer 7

In Flutter mobile applications the version number is in pubspec.yaml file. like below:

version: 1.0.0+1

To get the version name and code, add the package_info dependency into pubspec.yaml file, like below:

dependencies:
  package_info: ^0.4.0+16

And

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

Future<void> _initPackageInfo() async {
    final _packageInfo = await PackageInfo.fromPlatform();
    setState(() {
          String AppName = _packageInfo.appName;
          String PackageName = _packageInfo.packageName;
          String AppVersion = _packageInfo.version;
          String BuildNumber = _packageInfo.buildNumber;
          String BuildSignature = _packageInfo.buildSignature;
    });
  }
