How to Use
Get OS Version:
String platformVersion;
// Platform messages may fail, so we use a try/catch PlatformException.
try {
platformVersion = await GetVersion.platformVersion;
} on PlatformException {
platformVersion = 'Failed to get platform version.';
}
Get Version Name:
String projectVersion;
// Platform messages may fail, so we use a try/catch PlatformException.
try {
projectVersion = await GetVersion.projectVersion;
} on PlatformException {
projectVersion = 'Failed to get project version.';
}
Get Version Code:
String projectCode;
// Platform messages may fail, so we use a try/catch PlatformException.
try {
projectCode = await GetVersion.projectCode;
} on PlatformException {
projectCode = 'Failed to get build number.';
}
Get App ID:
String projectAppID;
// Platform messages may fail, so we use a try/catch PlatformException.
try {
projectAppID = await GetVersion.appID;
} on PlatformException {
projectAppID = 'Failed to get app ID.';
}
Get App Name:
String projectName;
// Platform messages may fail, so we use a try/catch PlatformException.
try {
projectName = await GetVersion.appName;
} on PlatformException {
projectName = 'Failed to get app name.';
}

void main() => runApp(new MyApp());
class MyApp extends StatefulWidget {

String _projectVersion = '';
String _projectCode = '';
String _projectAppID = '';
String _projectName = '';
@override
initState() {
super.initState();
initPlatformState();
}
// Platform messages are asynchronous, so we initialize in an async method.
initPlatformState() async {

// Platform messages may fail, so we use a try/catch PlatformException.
try {
platformVersion = await GetVersion.platformVersion;
} on PlatformException {
platformVersion = 'Failed to get platform version.';
}
String projectVersion;
// Platform messages may fail, so we use a try/catch PlatformException.
try {

} on PlatformException {
projectVersion = 'Failed to get project version.';
}
String projectCode;
// Platform messages may fail, so we use a try/catch PlatformException.
try {

} on PlatformException {

}
String projectAppID;
// Platform messages may fail, so we use a try/catch PlatformException.
try {

} on PlatformException {

}
String projectName;
// Platform messages may fail, so we use a try/catch PlatformException.
try {
projectName = await GetVersion.appName;
} on PlatformException {
projectName = 'Failed to get app name.';
}
// If the widget was removed from the tree while the asynchronous platform
// message was in flight, we want to discard the reply rather than calling
// setState to update our non-existent appearance.
if (!mounted) return;
setState(() {
_platformVersion = platformVersion;
_projectVersion = projectVersion;
_projectCode = projectCode;
_projectAppID = projectAppID;
_projectName = projectName;
