We assume that we have already installed flutter on our machine with older version of the flutter. So we have latest version of the flutter on the official website of the flutter. So how could we upgrade to latest version? To upgrade flutter to latest version we need to follow below steps
Open terminal and type the below command
|
flutter upgrade |
This will help us to upgrade
Flutter to latest version on the existing version
Flutter channel
|
#Flutter channels: #beta #dev #master #*stable |
Suppose if we want to live in the cutting edge? It’s easy to switch channels
Flutter channel dev
|
#Switching to flutter channel ‘dev’… #… |
And execute upgrade again:
|
flutter upgrade |
Now we have latest flutter version
What is the difference between Flutter and Kotlin

| Supported Platforms | Android, iOS, Google Fuchsia, Web, Linux, macOS, Windows | Android, JVM, iOS, macOS, Windows, Linux, JavaScript, WebAssembly |
| Learning Curve | Must understand Dart to build an app | More similar to Java, C#, Python, JavaScript. So, very easy learning curve |
| Language Stack | Uses Dart programming language | It’s itself a programming language that uses JVM, Java, JavaScript, and Native to build apps |
| App Performance | It gives an amazing performance. Since it uses Dart, it doesn’t require using JavaScript to build connectivity for interactions with the app. | Since it uses JavaScript and is 100% interoperable with Java, it offers a slow performance compared to Flutter. |
| Hot Reload | Supported | Not Supported |
| App Size | Bigger | Minimum size as compared to Flutter |
