<b>Why you should use Flutter for MVP development?</b>
What is Flutter? How Can it Help in Building an MVP?As a cross platform development framework, Flutter was developed with the objective of building native Android and <a href="https://solaceinfotech.com/blog/swift-3-migration-for-ios-app/">iOS applications</a>, using a single code-base. Flutter has attracted attention in several software development companies. It accompanies upgraded features, widgets and bug fixes. Being open source, it complements MVP development.Reasons for an increasing popularity of Flutter include:Flutter has a large community and supporting the usersBusiness firms need not spend large amounts as licensing fees during experimentationApp development becomes simplified, as Flutter speeds up the processA great user interface helps in creating an interactive user interface.Building an application with Flutter shows that new companies and business firms enjoy a dynamic setup. The dedicated widget engine in this cross platform tool attracts UI components that look like the native ones. UI developed using Flutter’s widgets are flexible and pleasing. These can be improved. These UIs are all around structured. The developers can customize the existing widgets, making custom ones. Flutter applications are known for their smooth and fast performance.What Makes Flutter a Good Choice for MVP Development?Flutter can eases the development of cost effective MVPs in various ways. Because of the availability of widgets, developing an application with Flutter turns out to be simple. The developers can incorporate the changes consistently. Developers can avoid the complex process of decision making with respect to the best business platform, while building a cross platform application. Hence you can obtain feedback from many respondents. Due to this MVPs are important for startups. Moreover, Flutter gives you the chance to make important integrations. The sketch design can be exported directly to pixel perfect codes. Instead of making changes in the visuals, one can organize delivering value. Flutter also enjoys a great compatibility with Firebase. This gets rid of the need to have a different backend for building a simple MVP.Ways in Which Flutter Can Help in Developing an MVP-Mobile application developers have discovered certain unique features in Flutter, which they can’t appreciate somewhere else. The flexible UI, speed, simple integration and performance are the main reasons behind its popularity.Let’s see how developers are being benefited by Flutter, when they work on MVPs.1. Developing cost effective apps-Previously, cost constraints used to be one of the key drawbacks for organizations willing to launch new applications. However, Flutter has discarded this issue, given that it comes free of cost. It supports the development of cross platform applications, where it is necessary for the developers to write a single code base. This serves the purpose for both Android and iOS stages. This has facilitated the process of working on both platforms and one can simultaneously develop applications, decreasing cost. Flutter allows developers to access features of native apps. This makes the tools pixel perfect. Large companies and small businesses benefit from the cross platform app development features of Flutter. Simultaneously, they need minimal money and time to access the mobile world.2. Speedy app development process-While building a finished product, developers require lesser time, due to flutter. It accompanies the hot reload feature, which allows the developers to see changes that have been made to the application coding spontaneously. When any change is made in the software, the developers can see it immediately. In this manner, the application development process turns out to be quicker and simpler. Flutter also encourages a closer collaboration between designers, developers and testers, when they need a quick change, improving…

Flutter best practices for building UI
Hi there, I am new to flutter development and I have probably stupid question... But here it is:Is there an best practices for building flutter UI? I am struggling to build pretty and responsive UI in flutter due to huge numbers of 'variables' - the same ui can be built in 3-4 different ways.I found that my approaches are usually ok in the first phase of development. But when start combining the widgets in order to create app for every device size it starts to overflow the screen size.Does anybody have an advice regarding the principles that I should stick to?Thanks

How to clear AsyncMemoizer memory ?
How to clear AsyncMemoizer? I need to refresh my tab controller screen after it's opened. But it's not getting updated because the Memoizer isn't allowing me to update the current state of the screen, I have used AsyncMemozier because my futurebuilder was going in a loop in a provider because of notifylisteners, And I was calling my method from a stateful Futurebulider.

Vscode extension for Generating Boilerplate code when using FilledStacks' architecture guide
I have been following FilledStacks' architecture guide for my flutter projects. I felt that it involved a lot of boilerplate to get the project started, which inspired me and one of my colleagues to publish an extension for vscode that generates this boilerplate code.We have published it to the VsCodeMarketplace today and will be looking forward to feedback and criticism. For some reason, it does not appear in the Extension list in VsCode unless the entire name of the extension is typed out.https://marketplace.visualstudio.com/items?itemName=madhukesh040011.flutter-mvvm-architecture-generatorLet us know what more we can add and fix.

Navigator with PageView - PageController
Hello everyone,So i am trying to build an app with a bottom navigator and swipable style pages (like snapchat but with the bottom navigator). What i am having trouble is navigation, specifically with push and pop. I would like it to work kinda like instagram (at least on android). You start on the home page, then if you click search and then the back buttom, it takes yo home, no to the previous page (assuming the main page is only one widget)My question is, is there a way to add a route to the navigator on change in a pageview? Is there another way to do this? I kind of want the animation that comes with pageView.Thanks!

Offline geolocation using flutter
Hello guys! so I am trying to get a flutter app to pretty much do what the geopoint-location lib does ( https://pub.dev/packages/geopoint_location ) only do it offline. that is - take device geolocation coordinates and output the region name. how would you suggest doing that?From what I understand this geopoint-location package uses some sort of web database to retrieve the region name, since it didn't work if the device is offline.My idea is perhaps try using this package, only connect it to a device storage database (perhaps not storing the entire database but only GETting small chunks of it from the server). since I am new in flutter / dart I'd love to get any input from you guys, thanks!edit: would be cool if you could direct me to resources on how to build / edit / find such a database that holds world regions names and perimeter (be it polygons or whatever).
