Flutter – Getting Started

Flutter Overview:

Flutter is Google’s UI toolkit for building beautiful, natively compiled applications for mobile, web, and desktop from a single codebase.

Flutter has an awesome feature called “HOT reload” which reduces half of the time required to run/debug the applications, ultimately helping rapid development.

The most popular Hamilton musical app was developed in Flutter  “in 3 months and had 1M+ installs”.

“Dart is the language used for flutter” with “used to develop Flutter apps”  and Dart itself has an “ART” hidden in it.

The first version of Flutter was codenamed “SKY” and ran on android OS.

Flutter 1.0 was launched on Dec 4th 2018.

For users Flutter makes beautiful app UIs come to life.

There are no such application frameworks that allow sharing both the UI code and  UI itself besides Flutter.

A summary of all the announcements in flutter interact is available here (blog.codemagic.io/flutter-interact)

Flutter has following pro/advantages over native development:

1. Same UI and Business Logic on All Platforms

There are no such application frameworks that allow sharing both the UI code and the UI itself besides Flutter.

2. Reduced Code Development Time

From my experience, building a mid-size Android app takes at least 40 seconds to get shipped onto the test device. And sometimes, it can take forever just to adjust a small visual aspect in the layout

3. Increased Time-to-Market Speed

This one is pretty straightforward. Flutter development framework functions quicker than its alternatives. In most cases, you can expect a Flutter app to require at least two times fewer man-hours compared to the same app developed separately for Android and iOS. 

4. Similar to Native App Performance

Application performance is crucial for good UX. While it’s hard to tell the exact figures, it’s safe to say that Flutter application performance in most cases will be indistinguishable from the native app and even better in complex UI animation scenarios.

5. Custom, Animated UI of Any Complexity Available

One of the biggest advantages of Flutter is the ability to customize anything you see on the screen, regardless of how complex it may be. While it’s usually possible to do a very custom UI on the native platforms as well, the amount of effort required differs by the order magnitude.

6. Own Rendering Engine

Flutter allows you to do so much stuff with your apps that aren’t available on other platforms. Obviously, it requires the framework to be pretty powerful. In fact, most of the points presented above wouldn’t be possible without a high-performance cross-platform rendering engine.

7. Simple Platform-Specific Logic Implementation

Besides the UI, many real-life mobile applications rely on advanced OS-level features, such as fetching GPS coordinates, Bluetooth communication, gathering sensor data, permission handling, working with credentials, etc. Many of these are available when developing a Flutter application through a ready-to-use plugin supported by Google.

8. The Potential Ability to Go Beyond Mobile

With Flutter, you can go far beyond Flutter app development on mobile. There’s also Flutter for Web and Flutter Desktop Embeddings now.

Steps to use Flutter:

STEP 1: Download Android Studio (Download Location: https://developer.android.com/studio/  )

STEP 2: Install Android Studio

STEP 3: Download Flutter SDK (Download location: https://flutter.dev/docs/get-started/install )

STEP 4: Unzip Flutter Folder

STEP 5: Go to android studio in file select settings.

• In that choose plugin
• Search plugin for flutter and install.

STEP 6:  Go to android studio and click on file select settings.

• In that choose Languages And Frameworks
• Set Flutter SDK PATH

Now it’s Hot Reload Magic Time:
