Flutter 2 comes with the beta release of Google Mobile Ads for Flutter, a new SDK that supports AdMob and AdManager to offer a variety of ad formats. It is a new plugin that provides native ads, inline banners along with existing overlay formats.

Null Safety In Dart Language:

Null safety is one of the important concepts and major productivity features in the programming language that simply helps developers avoid null errors. Null safety distinguishes nullable types from non-nullable types, strengthening type systems and making developers’ jobs easier. Dart’s latest version, Dart 2.12 features a stable version of sound null safety.

It prevents null error crashes by checking for null errors during development time, saving the app from crashes in production.

Dart 2.12 Version In Flutter 2:

Flutter 2 uses Dart 2.12. Dart’s latest version is released recently with sound null safety and FFI. Dart was trying to add null safety since the introduction of the sound type system in Dart 2.0. Dart 2.12 offers null safety as an opt-in feature, which simply means, you can use Dart 2.12 without being forced to use null safety. They also help migrate your code to null safety in an efficient manner.

This makes dart programs smaller and faster. Dart ensures your non-nullable variables are never null, hence, making a safe environment for the developers to prevent the potential crash that null can trigger.

Flutter Folio: Platform Adaptive Apps

Flutter’s cross-platform support is outstanding. It supports three platforms for production apps (Android, iOS, and the web) and three in beta (Windows, macOS, and Linux). Flutter Folio, a simple example app – scrapbooking app that showcases how Flutter apps run on multiple platforms from a single code base.

Flutter Folio is self-adaptive as it adapts well to the platform it’s running upon. You can check the Flutter Folio app that is built in collaboration with gskinner, an award-winning design team based in Canada.

AutoComplete And ScaffoldMessanger: New Widgets

Flutter 2 comes with two new widgets, AutoCompleteCore and ScaffoldMessenger. AutoCompleteCore provides the functionality required to get auto-complete in your Flutter app. It is one of the most-requested features for Flutter.

The ScaffoldMessenger was created to deal with a number of SnackBar-related issues.
