Is there a way to auto select keyboard language?
There was a feature in iOS Duolingo where, if you're typing in exercises in foreign language, the app will auto select the keyboard of said language, if installed. E.g. if you're typing in Swedish exercise and has Swedish keyboard installed, it will automatically bring up Swedish keyboard for you, no matter which keyboard you were previously using. Is this feature doable in Flutter?What I'm trying to achieve is to auto select English keyboard or whatever keyboard that can only input Latin alphabets in some fields. I've tried 'keyboardType' but even 'TextInputType.Password' won't auto bring up alphabetic keyboard. In Swift there's an 'alphabet' option in textField.keyboardType, but it's missing in flutter. I'm not sure if it's due to android lacking this feature.

Dart/Flutter sound null-safety good enough??
Hello everyone,I would like to start a discussion if the new “sound null-safety” is enough or if dart/flutter should go even further to a “sound language” (whatever that means)?First of all, coming from iOS/MacOs development with Swift/UIKit/Swiftui, flutter is very exciting and fun and first impression is great. None the less even after this new “sound null-safety” which is a good start, Swift seems to be the much safer (better?) language.For me the idea behind null-safety is making your program much safer and crash less often. But null-safety only treats part of the problem. Let me explain why:EXAMPLE1

exam1(i) { var n1 = i + 4; // should this be okay? int n2 = i + 4; // this compiles int n3 = 4 + i; // this does not } 

In my dream world this code should – from a safety standpoint – not compile. Adding the integer 4 to anything that I put in and it is okay with that?? This is madness! Creating an integer from anything plus 4 is okay? Strangely enough 4 plus anything is not okay?The language should force me to use specify types everywhere! Leaving it blank to mean “dynamic” should not be an option. Being explicit is key! “Yes I want dynamic type here” / “Oops you are right, the input/var should be an int”.If I use dynamic type, it should again force me to cast it to an integer before use and provide a default value if that fails.EXAMPLE2

void exam2() { List<int> nums = [1, 2, 3]; int n1 = nums[8]; // not safe (crash) int n2 = nums.elementAt(8); // not safe (crash) // something like this should be possible if nullable types were used instead of exceptions and it would be safe //int n3 = nums[8] ?? 5; //int n4 = nums[8, default: 5]; //int n5 = nums.elementAt(8) ?? 5 //int n6 = nums.elementAt(8, default: 5) } 

Why is there no easy and short why to access a list in a type safe way (without comparing index to list length)? If indexing a list or using elementAt provided a nullable type (e.g int?) you can work with lists in a 100% type safe way and even specify a default value if the index is out of range.Dart should make more use of nullable types and less exceptions. Exceptions crash your program (if not handled); using nullable types and null-safety prevents this.EXAMPLE3

void exam3() { List<int> nums = [1, 2, 3]; int n1 = nums[8]; } 

Calling a function should always (99.99%) be safe. Other programming languages have keywords like “throw/throws/throwing” to indicate that a function call is not save and you need to handle errors. For me it is super annoying that I cannot be sure that the function I call is safe and I might have to dig into the documentation for details. Again, having the language/compiler force me to specify throwing functions with a keyword and to handle those exceptions provides safety!There should be some keyword that indicates if a function/method can throw an exception so the compiler forces you to handle these to provide safety.​Sound null-safety is a great start but there is much more a language can do to prevent bugs/errors/crashes.I think in a “sound language” the program should not be able to crash unless the programmer explicitly allows it!This is only my opinion that is heavily influenced after using swift for many years.Do you think this is something that is planned for dart (maybe 3.0?), or do you think that the new “null-safety” is safe enough and the dart/flutter team will not improve safety much more??

What is wrong with the video and image format support in flutter?
The last time I checked which was about almost a year back the support for standard formats like MP4 and HEIC (standard image format under iOS) was terrible. I'm concerned that it still is! What bothers me even more is that the new Apple ProRAW format well probably never be supported (considering that HEIC is used for years as standard and still isn't supported).Does anybody know about improvements in this area? I mean the next big cross-platform framework should at least support the major formats like jpeg, png, webm, mp4, mov, raw and probably some more.What do you guys think?

Try your banking website, then try this Flutter web app
There was a recent tweet sharing a payments webapp built in Flutter Web. I tried it and was blown away. I'd just come from using my bank accounts and the web app felt so smooth by comparison. If I didn't read that it was built with Flutter Web, I'd never have been able to tell.https://moi.codemate.devAt Codelessly, I've built a few websites in Flutter and we're building a Flutter UI builder web app in Flutter but we've always targeted mobile apps. Now, it's amazing to see how performant Flutter Web can be (albeit in Chromekit browsers) so it looks like we'll be supporting web apps too.
