help with a test code
I went through with the Codelabs examples: https://ift.tt/32KnZI6. Then I copied the code into a local new project with main.dart as: // import 'dart:async'; import 'package:flutter/material.dart'; // import 'package:flutter_test/flutter_test.dart'; void main() {

Flutter Web: Complete Gaming Hosting Service
Hello Flutter devs,I have just finished developing a gaming hosting service site using Flutter Web, the source code is available on Github and I wanted to share my experience.Before I start it's important to know that I'm not a professional dev and I'm very new to web development, coding is my passion and I'm just in high school, though I've always focused on mobile, desktop and backends using languages like Java, Kotlin, C++ and C#, so I don't really have a point of reference to determine if flutter web has the potential to be better than other web frameworks.First of all, it's clear from the very start that Flutter Web is in beta: scrolling is terrible on mobile devices, mostly on firefox, but it sometimes also happens on Chrome Mobile, Desktop browsers will not suffer from this problem. Now, this is not a problem if your web app uses scrolling in small widgets, but if the whole thing has to scroll prepare yourself for some trouble. I've opened an issue on GitHub, but I noticed that there are at least three that present a similar problem, no solution was found to this day for the issue in the engine. Though SKIA(Web Assembly) seems to fix this, but while it fixed scrolling performance, it breaks everything else from the Navigator to the page loading times. In the end, I was able to bring 60 fps scrolling to desktop, chrome mobile, but firefox mobile still seems to struggle.The app is built to scale for all screens as visible from the source code, this works perfectly, so the app is reactive.The site can become a PWA, no code was needed, honestly, I didn't even realize that it was a thing until I saw a talk on the Flutter channel lol.Developing the site was just a fantastic experience: developing for the web is as easy as for mobile(excluding that weird problem that drove me crazy), hot reload works as expected, the webserver option is really nice.In the end, Flutter Web is probably not production-ready, but with better Web Assembly Support(SKIA), instead of dart2js, and with the scrolling bug fix it could easily become the best frameworks for web development.Some screenshots:Desktop: https://imgur.com/a/mbi4jrnMobile: https://imgur.com/a/ORYDYOG

New package: Drag-and-drop reordering of two-level lists
I've just released my first flutter package for drag-and-drop reordering of two-level lists: drag_and_drop_lists.Github repo.This is useful for when you have a list of lists that should be reorderable. For example, a trello/kanban board or when you would like to drag a new item into a list from outside of the list itself.Unlike other reorderable list packages like reorderables, ReorderableListView, or draggable_flutter_list, this package supports reordering items between multiple lists, and reordering individual lists as well.Other features include:Many formatting options
Expandable/collapsible lists
Drag in lists or items from outside of the widget
Slivers supported
Extensive examples
If you like it, please support my work by leaving a on the Github repository!

How to wait for async Future function to finish before building widget in scaffold?
Hi, My main.dart is using android_path_provider package to get the documents path. This path is then passed to another class (stateful widget) which reads files from this path. The problem is that sometimes, the document path does not update in time and widget build fails as it does not get

How to save changes made to text file after opening it using File.readAsString()?
Hi, I have a text file in memory that I open using File.readAsString().. This extracts the text from it and saves it as a String. This is given to a TextField() so that changes can be made to this text. How do I effectively save these changes back to the original file? Here is my code so far.
