Moved to our Android forum.

Please explain what sort of bugs you are creating.

You can create great apps with any language, and you can create buggy apps with any language. In other words: the choice of language has nothing to do with how buggy an app is going to be.

Flutter only makes sense if you need to create both iOS and Android apps, AND you can justify having developers learn a language (Dart) that is otherwise little used. For Android-only, Kotlin is the language of choice.

I just upgraded flutter to 2.0, lot of code have changed.
One of the example is the color of border
Before upgrade, we can assign as below

 border: Border.all(color: Colors.grey[300]), 

Now need change to

border: Border.all(color: Color(0xFFE0E0E0)),

Assume I have  defined 100 Container with different color of border, this upgrade require me change the code one by one..

Does your IDE not have regexp search-and-replace across all files? That should be able to handle this. Or if it has a Dart/Flutter plugin, it may have a refactoring that takes care of this.

I can't find a way to do it.Between there have lot of plugin have not been upgraded to null-safety which caused lot of dependency error. I think better stick to 1.22.6 version for now.

Hi Randy Tong,

I haven't upgraded to Flutter 2.0 yet but I don't think it's mandatory to use hex instead of Material's constant colors. You've probably used a conversion guide that prefers to use 0xff. Portability is maintained, there are a lot of projects in Flutter that use Material colors instead of hexadecimals so it would be a big mistake not to be able to implement them.
Surely you will find info on the Material website. Trying costs nothing, we write the code but a thorough reading of the various because it is always useful.
