It's almost asked to me thrice in recent interviews. Usually I explained about local authentication, prevent screenshots and flutter secure storage. But it has more than that. Yes, Flutter is completely new. Securing native apps would be more comfortable to do. But actual things, you can do more that in flutter. We can see that step by step. 1. Flutter Secure Storage Securing Data is very important. Using key value pair, you can achieve it. It's similar like shared_preference, but it can encrypt and decrypt data.  2. Obfuscate code For android, usually will do these stuff in ProGuard.  In app.gradle: android { ... buildTypes { release { signingConfig signingConfigs.release minifyEnabled true useProguard true proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } } } i n /android/app/proguard-rules.pro: # Flutter -keep class io.flutter.app.** { *; } -keep class io.flutter.plugin.**  { *; } -keep

 Hey friends, good noon. Rainfall on summer here, It's unusual. Let's see the difference between dependencies and dev dependencies in flutter. Dependencies: Included in your app during compilation.  Dev Dependencies: Can use on while developing the app on development stage. Like testing. Doesn't include any inside the apk.

Hello friends , It's been more than a year without any post. Sorry for that, heavy busy and not single any more. so now I kickstart my active routine again. So let's play.. So I spent more than 2 years in flutter development, learning a lot of concepts and new stuff. Now we see some little spark on that.  LocalAuth It's a local authentication library and we can use it in both android and iOS platforms. Fingerprint biometrics, PIN, Pattern and face unlock works well. As far as I know, It's perfectly fine on iOS. but on android it's a little bit laggy on when I change the state anyhow. It's cool. IntroSlider Flutter Intro Slider is a flutter plugin that helps you make a cool intro for your app. Creating an intro has never been easier and faster. It's a good library which I tried recently.
