Setting custom values to Enums in Dart

I do not remember where I got it from, but yes, it's possible. This sample shows all there is to know about it: https://github.com/atn832/kanji_dictionary/blob/2d9b2332303440ac6858040394ed6cf91c05d964/lib/src/book.dart Lazy post. Hope it helped! :)

Getting started with Pixel Art

Here is what I've learned from https://www.coursera.org/learn/pixel-art-video-games. You can audit the class for free by clicking "Enroll for free", then choosing "Audit for free". I am using piskelapp.com. It's free and really well made. Unlike Photoshop where you need to pick the right presets

Fixing `DVTPortalServiceErrorDomain: Your session has expired` in Flutter for iOS

These days my iOS app updates for Flutter keep randomly failing with the following error: DVTPortal: Error: Error Domain=DVTPortalServiceErrorDomain Code=1100 "Your session has expired. Please log in." It used to be about once every 5 builds, but then it became 100% of them failing with that error. So

Making a list of Korean vocabulary for beginners

I've found that the biggest deterrent for using my Flashcards app was that it came with no content. So I decided to make a few lists of words for beginners. I really like KANJIDIC's list of Kanji tagged with which grade Japanese students study them. So I looked for a

Converting a List<int> to a String in Dart

I first tried using this: String.fromCharCodes But it mangled the UTF-8 encoding, even though the doc mentions something about UTF-16. For example, it mangled: 亜 Into: äº It turns out I should have used this instead: import 'dart:convert'; utf8.decode(list);

Profiling a Dart CLI app

I had some trouble finding the docs for it, so I'll give you the right link: * At https://dart.dev/tools/dart-devtools, they link out to Flutter's CPU profiler. * https://docs.flutter.dev/development/tools/devtools/cpu-profiler. There's a few gotchas. First you need to enable the Profiler after the

Fixing EXCEPTION CAUGHT BY FLUTTER TEST FRAMEWORK in testWidgets with FutureBuilders

I have a FutureBuilder that checks for errors and displays an error message.

In which order should I study Kanji?

I recently got back from a trip to Japan and it made me want to learn basic Kanji again. It would help decipher restaurant menus and navigate the city. Besides it's really fun to figure it out. This a-ha feeling never gets old. As soon as I got back home,

Fixing the boxes in screenshot tests in Flutter

Mocking http.Client

Mocking http.Client is well documented, yet it didn't go as smoothly as expected. I'm following the guide at https://docs.flutter.dev/cookbook/testing/unit/mocking#3-create-a-test-file-with-a-mock-httpclient. My first change compared to the doc is that I did not import http as http, because I don't have any conflict.

The short answer is no. Here's a few more details. Before I tried it myself, I googled and ended up on a conversation on the FlutterFlow forums, but it doesn't really give any real information. So I won't link to it. The only relevant piece of info is an Admin

FlutterFlow provides two built-in components to display HTML, but they can't display local HTML with Javascript: * HtmlView only supports HTML and CSS parsing. It does not run Javascript. * WebView only supports remote URLs. In order to display HTML with Javascript support, one has to use a custom Widget. I asked

This error has been going on for a while. It is not too bad since it is just a warning, not an error. So it does not prevent compilation. Still, after all this time, I expected the Google team, author of the package, to have fixed it by now. This
