install_plugin

A flutter plugin for install apk for android; and using url to go to app store for iOS.

Usage

To use this plugin, add install_plugin as a dependency in your pubspec.yaml file.

/// for Android : install apk by its file absolute path; /// if the target platform is higher than android 24: /// a [appId] is required /// (the caller's applicationId which is defined in build.gradle)staticFuture<String> installApk(String filePath, String appId) async {
Map<String, String> params = {'filePath': filePath, 'appId': appId};
returnawait _channel.invokeMethod('installApk', params);
}
/// for iOS: go to app store by the urlstaticFuture<String> gotoAppStore(String urlString) async {
Map<String, String> params = {'urlString': urlString};
returnawait _channel.invokeMethod('gotoAppStore', params);
}

Example

For Android, you may need to request permission for READ_EXTERNAL_STORAGE to read the apk file. In the example, I used the permission_handlerplugin.

import'dart:async';
import'package:flutter/material.dart';
import'package:flutter/services.dart';
import'package:install_plugin/install_plugin.dart';
import'package:permission_handler/permission_handler.dart';
voidmain() =>runApp(newMyApp());
classMyAppextendsStatefulWidget {
@override_MyAppStatecreateState() =>new_MyAppState();
}
class_MyAppStateextendsState<MyApp> {
String _appUrl ='';
String _apkFilePath ='';
@overrideWidgetbuild(BuildContext context) {
returnnewMaterialApp(
home:newScaffold(
appBar:newAppBar(
title:constText('Plugin example app'),
),
body:newColumn(
children:<Widget>[
TextField(
decoration:InputDecoration(
hintText:'apk file path to install. Like /storage/emulated/0/demo/update.apk'),
onChanged: (path) => _apkFilePath = path,
),
FlatButton(
onPressed: () {
onClickInstallApk();
},
child:Text('install')),
TextField(
decoration:InputDecoration(hintText:'URL for app store to launch'),
onChanged: (url) => _appUrl = url,
),
FlatButton(
onPressed: () =>onClickGotoAppStore(_appUrl),
child:Text('gotoAppStore'))
],
),
),
);
}
voidonClickInstallApk() async {
if (_apkFilePath.isEmpty) {
print('make sure the apk file is set');
return;
}
Map<PermissionGroup, PermissionStatus> permissions =awaitPermissionHandler().requestPermissions([PermissionGroup.storage]);
if (permissions[PermissionGroup.storage] ==PermissionStatus.granted) {
InstallPlugin.installApk(_apkFilePath, 'com.zaihui.installpluginexample')
.then((result) {
print('install apk $result');
}).catchError((error) {
print('install apk error: $error');
});
} else {
print('Permission request fail!');
}
}
voidonClickGotoAppStore(String url) {
url = url.isEmpty
?'https://itunes.apple.com/cn/app/%E5%86%8D%E6%83%A0%E5%90%88%E4%BC%99%E4%BA%BA/id1375433239?l=zh&ls=1&mt=8': url;
InstallPlugin.gotoAppStore(url);
}
}
