What is Flutter?
If I had to express Flutter in my words, I would say, it is the latest Hybrid mobile application environment functioning like native apps and Flutter is a first material design cross-platform developed by Google.
Flutter is an open source development environment embedded with a material design concept which gives the life to modern app designing with ease.
What is material design?
Material Design is a concept, which gives a magic wand in the hands of mobile application designers. With this, they can find a number of pre-built designs and modification functionalities. Google has included material design in flutter mobile app development platform to craft high-level UI experience in no time. This combination helps us to create a dynamic and stunning UI without many efforts.
Ionic Cordova V/s Flutter
Advantages of Flutter over Cordova/Ionic
1. Unlike Cordova/Ionic, which use webviews, it uses Widgets which have the fast rendering and also resolve the problem of poor UI performance. This is one of the major advantages of the Flutter app development platform because the webview components may not appear consistent on different devices or on different screen resolutions.
2. It provides hot reload feature in the development stage that means there is no need to re-install the application after making any changes.
3. Its dart package library provides firebase plugins, which are beneficial tools. Firebase also has its own features like live rendering(if any change is made in firebase db it will automatically reflect on the application) and it also provides fast database communication speed at the time of fetching/sending data.
Can we attach a NodeJS server with flutter application and does it have performance difference while using Google firebase as backend?
Yes, we can attach an existing nodejs server with a Flutter app it will work similarly as Cordova/Flutter app or even better.
Undoubtedly, Google firebase is way faster backend, and it also has live reloading feature which makes it faster, but it is not a free tool, we have to pay some amount for its services and if you have an existing backend and don’t want to spend extra money on the additional backend. So, I will suggest you stick to the existing backend.
Yes, Flutter has a PDF viewer which we can use to display PDFs after authentication and we can also give options to perform some actions.
