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_handler plugin.
please push you demo apk in /storage/emulated/0/Android/data/com.youxiachai.installpluginexample/files/
void main() => runApp(new MyApp());

class MyApp extends StatefulWidget {
@override
_MyAppState createState() => new _MyAppState();
}

class _MyAppState extends State<MyApp> {
String _appUrl = '';
String _apkFilePath = 'demo.apk';

@override
Widget build(BuildContext context) {
return new MaterialApp(
home: new Scaffold(
appBar: new AppBar(
title: const Text('Plugin example app'),
),
body: new Column(
children: <Widget>[
TextField(
decoration: InputDecoration(
hintText:
'appdata files apk file name to install. Like demo.apk'),
onChanged: (path) {
_apkFilePath = path;
},
),
TextButton(
onPressed: () {
onClickInstallApk();
},
child: Text('install')),
],
),
),
);
}

void onClickInstallApk() async {
if (_apkFilePath.isEmpty) {
print('make sure the apk file is set');
return;
}
var permissions = await Permission.storage.status;
if (permissions.isGranted) {
var storageDir = await getExternalStorageDirectory();
final dirPath = storageDir?.path ?? '/';

final resultPath = '$dirPath' + '/' + '$_apkFilePath';

var file = File(resultPath);
var isExists = await file.exists();
print('onClickInstallApk _apkFilePath $resultPath exists $isExists');

InstallPlugin.installApk(
resultPath, 'com.youxiachai.installpluginexample')
.then((result) {
print('install apk $result');

}).catchError((error) {
print('install apk error: $error');
});
} else {
print('Permission request fail!');
}
}
}
