Custom Top Navigation Bar: Always show 'selectedTab' at the Center
Hi Community, I have a custom navigation Top Bar, consisting of 4 tabs, and it is linked to a PageView. When I tap on an item from the bar, or swipe left or right, the shown page is changed. Only 3 out of these 4 tabs are displayed at a time though, which means that let's say' I swipe/navigate

General question about model(s) for Flutter apps

Login with Telegram in Flutter App
Today I discovered that Telegram offers to developer also a “Login with Telegram” widget and I thought it would be really cool to add this in flutter apps.Sadly the official documentation only offers instructions for JavaScript (i think, I’m not sure 😅)Any ideas to use it in Flutter? Did anyone tried it so far?

Why would I want to use ChangeNotifierProxy provider?
I was reading the Provider documentation. I was specifically reading about the ChangeNotifierProxyProvider. It describes that its purpose is when one ChangeNotifier depends on another.Why do I need to use provider ChangeNotifierProxy when I can just do the following...

import 'package:flutter/widgets.dart'; 

class CounterModel extends ChangeNotifier { int count = 0; void increment() { count++; notifyListeners(); } }class OtherModel extends ChangeNotifier { final CounterModel _cm;OtherModel(this._cm) { _cm.addListener(() { // do stuff here. }); } }I can then construct my ChangeNotifiers in main.dart, and OtherModel will be updated of changes to its CounterModel.I assume there are some uses cases that I am missing. Can anyone enlighten me?

Is there a way in Flutter desktop to be able to listen for controller inputs?
Hi everyone!I know that it's possible to listen for keyboard activity. However with the advent of Flutter desktop, I can imagine that a lot of OS support still isn't quite covered yet.My idea was it would be cool to be able to visualize in Flutter a flight controller (Specifically i have the Saitek X52 Pro in this case).And i believe that I can bind all of the buttons and switches to key's on the keyboard, but I have no idea what to do with reading the analog signal from the flight stick and thrust controller.I would really love to create some cool sci-fi UI's in flutter that take advantage of custom controllers with analog inputs and thought it could be a fun project.Any ideas?

<b>Flutter as Web SPA framework: dare to use it instead of Angular or React?</b>
<strong>TL;DR</strong> it is doable, there're rough edges, Flutter is cleary not 'native' to the web world (unlike Angular) and not completely tailored to Desktop developmentIntroDuring a Flutter workshop that demonstrated how easy it is to build an app for 6 platforms we discussed the most common cases and concluded that the range of supported platforms is great, but not a killer feature. In a realistic scenarious one might need apps for Android and iOS (optionaly PWA) that have same UI. Then there should be an SPA Web app tailored to Desktop screens (and thus having different UI and richer features). There're tools that fit nicely both of the cases and having same tools used for both Mobile and Desktop development might not be that beneficial.A question emerged, if we used Flutter as a web framework to build SPA for desktop instead of Angular or React, what would it be like?Few weeks latter in my company we started a PoC rewriting small part of a legacy app (AngularJS, Node.js, OData) to a new tech stack (Blazor WASM, .NET 5, gRPC). I decided why not try my Flutter skills and build a second client PoC. Sharing my experiences here...DemoBelow are 2 links of the Flutter client I've built:HTML Renderer: <a href="https://maxim-saplin.github.io/flutter_web_spa_sample/html/#/">https://maxim-saplin.github.io/flutter_web_spa_sample/html/#/</a>CanvasKit Renderer: <a href="https://maxim-saplin.github.io/flutter_web_spa_sample/canvaskit/#/">https://maxim-saplin.github.io/flutter_web_spa_sample/canvaskit/#/</a>And the repo: <a href="https://github.com/maxim-saplin/flutter_web_spa_sample">https://github.com/maxim-saplin/flutter_web_spa_sample</a>The apps are built with Flutter beta 2.2.0-10.1.preFeaturesCustom data grid (based on extended stock DataTable) with sticky header, pagination, sorting and Excel like column filters (pop-ups appear when cliking on column headers)Right click context menu for rows via custom widgetA hack to silence browser's context menu when doing right clicksChanging visible columns and saving the configuration to shared_preferences (gear icon)Localization via i18n_extension packageRouting via top menu and sharing 'Master page' between different content pages (there're 4 routes)Layout with fixed header/footer and expanding content areaCustom icons in TTF font generated from SVG (via <a href="https://icomoon.io">icomoon.io</a>) and bundled in assetsPopover/popup for advanced search (magnifier button)Adv. search and filter are implemented via custom_pop_up_menu packageIoC (switching fakes/ gRPC implementations) via Provider state managementflutter_hooks as alternative to StatefulWidgetgRPC back-end intergations and auth via JWT (though not used in demo, fakes turned on)Conditional imports for gRPC client to allow different implementations in Web/Native (gRPC Web Proxy is required for browser clients)EffortIt took me ~7 days (~56 hours) to complete the PoC:First weekend (2 days) to create the layout and customize DataTable to support sticky headersSecond weekend (2 days) to complete the UI fucntionality with mocks and properyl structure the codeAnother 5 days integrating with gRPC, troubleshooting, presenting auth, tinkering with UI etc.Before starting the project I had ~8 months of casual experience with Dart/Flutter doing small projects, as well as some React/Redux experience in 2018/2019.The developer working on the Blazor side (with experience in .NET and React, but not Blazor) spent 3 weeks doing the same client, though not completing it (e.g. no selection of columns, no localization etc.).Subjectively, Flutter was percieved as a very productive tool.Impressions/IssuesDebguing using VSCode (on both Windows and macOS) is very troubling: breakpoints are not predictable (sometime they don't fire, they keep firing event when removed), VSCode debugger occasionally refuses to show variable values.
