IOS Bug, keyboard not showing up.
We encontered a problem in IOS, we have tested many webview packages from https://pub.dev/ and all the solutions ends with the same result.When the innapp website opens, it loads perfectly, but when you interact with an input, the keyboard doesn't seems show up, it occurs in all the inputs from all the pages.Thanks in advance!.IMAGE of the errorThe error log output is: Probably at least one of the constraints in the following list is one you don't want.

Is Flutter the most ideal tech for a "Lime"(Electric scooter rental app)-like startup?
Hi people,I have been using Flutter for the past year and loving it. However I would like to get the thoughts of the community, especially the experienced developers who worked on production ready apps which require a large ecosystem of development. I think the feedback you give might be valuable to a lot of people/companies who are considering to use Flutter in a big project.If done with Flutter, what are the optimal guesses to the questions below: (Assume UI/UX design is ready along with assets, etc..)Is flutter OK for this project? (look at some of the project ingredients at the bottom of the post)How many Flutter developers are needed? (And what experience levels?)With a project of this size, what state management is best suited?Is Firebase OK for a project like this? (consider pricing while answering)How many Server side developers are needed?How many testers? (Unit tests will be written by the Flutter devs)How long for the MVP(minimal viable product) to be ready?How long needed for the App to be market ready?Please consider these requirements:(There might be some that I forgot to add. remind me if you want to add any)iOS/AndroidReal time info display(location of the scooters/battery levels/etc..)Payment servicesInternationalizingAccessibilityMaps and NavigationLocation PermissionCamera PermissionBarcode scannerPush NotificationsTestingAnalyticsCrashlyticsAnd things I forgotten to add...

Flutter winning me over SwiftUI
After spending some time with Flutter to create a mobile application for a small effort it was a pretty unique experience in that I really enjoyed the process with hot reload and being platform agnostic. I recently decided to give a try at SwiftUI and while its a great start it got very frustrating really quickly in that they don’t have a true hot reload feature and the structuring of an application was a mess. As a mainly iOS user it feels like I am cheating on a platform I have heavily invested in for a new more exciting development ecosystem.

<b>Recap: Google's BIG challenge, Make your Flutter app look gooooood &#128525;</b>
Hey, everyone! Here's a recap of what's been happening over the past couple of weeks in the Flutter-verse.We talk a lot about things like state management, so this time around we decided to highlight some of the awesome stuff Flutter allows us to do to make our apps look good and work well.Love it? Hate it? Let us know in the comments!Want to get it by email? <a href="https://flutterigniter.com/snacks/">Click here</a>.____Your Flutter app needs to look good and feel greatWe've all had designers that have asked for things that were just wayyyyy too complex. Thankfully, Flutter gives us some awesome tools that make it much easier to say “yes” to designers while keeping your code &#128170;&#8203;<strong>Export Flutter code from Zeplin</strong>...ever gotten a Sketch or Photoshop file from a designer and then had to manually figure out colors, sizes, etc? Yeah, it’s a pain in the a**. Thankfully, if you use <a href="https://zeplin.io/">Zeplin</a>, there’s a <a href="https://medium.com/flutter-community/flutter-and-zeplin-speed-up-the-development-process-from-your-design-45ff5d21166a">great extension from Roberto Juarez</a> that will automatically generate Dart code you can use in your Flutter app.&#8203;<strong>Easier Styling with Division</strong>...as you work with Flutter, you’ll undoubtedly run into some awkwardness with styling, whether it’s inconsistencies in how exactly you style different things (ex: centering vs. font size) or sharing styles among multiple widgets. The <a href="https://github.com/ReinBentdal/division">Division package from Rein Bentdal</a> aims to make it a whole lot easier using CSS-inspired syntax. Need a video tutorial? <a href="https://www.youtube.com/watch?v=kcq8AbVyMbk&feature=emb_title">Look no further</a>.&#8203;<strong>Cupertino “Stack View” is coming/already here</strong>...we’ve heard it called by many names: stack view, sheet presentation and more, but you’ve undoubtedly seen <a href="https://user-images.githubusercontent.com/3678732/66692450-05bb6d00-ecd1-11e9-8ba3-e6d5df09d645.png">this view style</a> if you’ve used iOS 13. While it’s <a href="https://github.com/flutter/flutter/issues/42560">been accepted</a> as a future inclusion in the Cupertino package, a fellow Flutter community member created the <a href="https://github.com/aliyigitbireroglu/flutter-cupertino-stackview">cupertino_stackview</a> package to make it a reality now.&#8203;<strong>Theming in Flutter...</strong>&#8203;<strong>&#127761; If your app doesn’t support Dark Mode, it sucks</strong>…okay, just kidding but dark mode is a feature that will most likely come to be expected in the future given that it’s now an OS-level option. So how do we do it in Flutter? In <a href="https://www.youtube.com/watch?v=G7gV89hnooM">this video</a>, Paul Halliday shows you how it's done using Provider.&#8203;<strong>Looking for a really in-depth theming tutorial?</strong>...if you’ve already read the <a href="https://flutter.dev/docs/cookbook/design/themes">Flutter theming docs</a> and are craving more, <a href="https://www.youtube.com/watch?v=RJkiESVJXAk&feature=youtu.be">check out this video from Techie Blossom</a> that digs deep into the theming process.&#8203;<strong>Want to create your app’s theme visually?</strong>...check out the <a href="https://rxlabz.github.io/panache_web/#/">Panache theme editor</a>. Start with a base palette, customize each widget style to your heart’s content and then copy the generated code. Done!____&#127906; Animate all the things…Animation is a powerful thing. Used too much and it can ruin a perfectly good app, but used just right, it can add a whole new dimension to the user experience. Intrigued? See the list below for animation tutorials for both the novice and the elite.&#8203;<strong>Understand the basics</strong>...with <a href="https://resocoder.com/2019/08/01/flutter-animation-tutorial…
