How good is Flutter?
Help post
I know some basics of React-native and heard flutter is better. And now I am confused about whether to learn (React and React-native) or flutter for web and mobile development. I heard that using flutter we can use the same code base for both webs, mobile apps, and desktop application development.
For eg, using javascript for the web we have to learn React, and for mobile apps, we have to learn React-Native. But with flutter, it works for both web and mobile apps. Is that true?

32+64 bit Android Flutter module and download app size?
Hey, we will be adding Flutter module to existing apo and I'm worried about potential increase of download size.Android studio reports increase in download size by about 18MB after adding Flutter. At the same time App Store build is increased by just 8MB.We publish only one APK to Google Play Store and maybe this is the problem. Should we generate and publish separately 32 and 64 bit versions to mitigate this issue?Or is Play Store smart enough to figure this out, cuz App Store is. In App Store Connect I have very detailed breakdown for every iDevice having different cpu architecture and screen density, but in Google Play Console I see only one number.Thank you

Can we view RTI images on flutter app?
Hello everyone, few weeks ago I started learning Flutter.Came up with a task which is, if I can manage to view RTI images in a flutter app in approximately the same way they are being viewed in WebRTIViewer (demo).I don't know how to move forward with this.Besides, the real question is, if this even possible? If not, can I code from scratch using Dart to build something which directs the users to a route where they can view the RTI images in the app itself?

Best practices when developing image resources API for Flutter clients?
What are the things to consider in your Flutter app when downloading image resources? Are there general image size resolutions for one size fits all (what are they?) or should device types be taken into consideration for your API when fetching images?

aes_crypt | A Dart library for encrypting/decrypting files, plain text and binary data in AES Crypt file format
Today I have published my first Dart package: https://pub.dev/packages/aes_cryptIt is a library for Dart and Flutter developers that uses 256-bit AES algorithm to encrypt/decrypt files, plain text and binary data. It is fully compatible with the AES Crypt file format and can be used to integrate AES Crypt functionality into your own Dart or Flutter applications. All algorithms are implemented in pure Dart and work in all platforms.

Futures, Streams and Firebase Billing
so my understanding is that using Firebase with futures will do single fetches, for example, with a press of a button, you get a list of products and that's it. With streams however, a connection is opened and any changes to the products for example a price change will instantly be reflected in the app whereas with futures, you would have to make another call to get the updated price.My question therefore is, since one approach is opening and maintaining a connection (streams) and the other isn't (futures), how do the two fare as far as Firebase billing is concerned? is one approach more costly than the other? assuming that you do everything right like disposing streams and stuff.

Creating Widget as a local variable?
I myself prefer to separate everything into its own StatelessWidget. However, I came across some code that initialize the widget as local variables and then use it. While I do not like it, but I am struggling to find a reason of why we shouldn't do it.``` class MainWidget extends StatelessWidget { final _firstText = const Text('first text'); final _secondText = const Text('second text');@override Widget build(BuildContext context) { return Column( children: <Widget>[ _firstText, _secondText, ], ); } } vs class MainWidget extends StatelessWidget { @override Widget build(BuildContext context) { return Column( children: <Widget>[ _FirstText(), _SecondText(), ], ); } }class _FirstText extends StatelessWidget { @override Widget build(BuildContext context) { return const Text('first text'); } }class _SecondText extends StatelessWidget { @override Widget build(BuildContext context) { return const Text('second text'); } } ``` Could any one give me a reason why we should do one to the other?
