Flutter App Development Course for Beginners 2026 (Hindi) - Null Safety in Dart - Flutter Course for Beginners #11

In this video, we will learn Null Safety in Dart from scratch and understand why it is such an important concept for every Dart and Flutter developer. We will start by understanding what null is and why it causes unexpected crashes in applications. Then we’ll see how Dart’s Null Safety system helps us catch these problems at compile time instead of runtime. You’ll learn the difference between nullable and non-nullable types, how and when to use null check (!), and how null-aware operators like ?., ??, and ??= work in real scenarios. --------------------------------------------------------------------------- Null Safety in Dart - Flutter Course for Beginners #11 #fluttercourse #dart #fluttercourse #dartcourse #appdevelopment #androiddeveloment #fluttercourse #iosdevelopment #fullstackdevelopment #crossplatform #multiplatform #nullsafety
