Flutter For Beginners

In plain English: So what the heck is Flutter and why is it a big deal?

Let me get this out there first: This article is meant to give you a general, extremely vague understanding of what Flutter is and why you should bother to care. It is absolutely not technical (or even technically correct) and it’s not meant to be. It’s meant to give you the general idea because you’re sitting there saying: “Why the heck is everyone is so worked up about this Flutter thing?”

Google I/O 2018 – Codelabs

Google Developers Codelabs provide a guided, tutorial, hands-on coding experience. Most codelabs will step you through the process of building a small application, or adding a new feature to an existing application. They cover a wide range of topics such as Android Wear, Google Compute Engine, Project Tango, and Google APIs on iOS.

Rethinking GPS: Engineering Next-Gen Location at Uber

Location and navigation using global positioning systems (GPS) is deeply embedded in our daily lives, and is particularly crucial to Uber’s services. To orchestrate quick, efficient pickups, our GPS technologies need to know the locations of matched riders and drivers, as well as provide navigation guidance from a driver’s current location to where the rider needs to be picked up, and then, to the rider’s chosen destination. For this process to work seamlessly, the location estimates for riders and drivers need to be as precise as possible.

Since the (literal!) launch of GPS in 1973, we have advanced our understanding of the world, experienced exponential growth in the computational power available to us, and developed powerful algorithms to model uncertainty from fields like robotics. While our lives have become increasingly dependent on GPS, the fundamentals of how GPS works have not changed that much, which leads to significant performance limitations. In our opinion, it is time to rethink some of the starting assumptions that were true in 1973 regarding where and how we use GPS, as well as the computational power and additional information we can bring to bear to improve it.

While GPS works well under clear skies, its location estimates can be wildly inaccurate (with a margin of error of 50 meters or more) when we need it the most: in densely populated and highly built-up urban areas, where many of our users are located. To overcome this challenge, we developed a software upgrade to GPS for Android which substantially improves location accuracy in urban environments via a client-server architecture that utilizes 3D maps and performs sophisticated probabilistic computations on GPS data available through Android’s GNSS APIs.

In this article, we discuss why GPS can perform poorly in urban environments and outline how we fix it using advanced signal processing algorithms deployed at scale on our server infrastructure.

FLUTTER IS THE FUTURE OF MOBILE APP DEVELOPMENT

“Flutter is a new mobile app SDK to help developers and designers build modern mobile apps for iOS and Android.” Modern, reactive framework allows us to build powerful UI with animations, shared codebase and views over iOS and Android platforms. It makes development process easier, development costs at minimal and rapid deployment. Flutter is build with C, C++, Dart and Skia. And the most beautiful part is that all release code is compiled in native code (Android NDK, LLVM, AOT-compiled) without interpreter involved. If you are familiar with performance drawbacks of hybrid frameworks you can easy say that flutter compile fastest code very close to pure native performance.

AWS AppSync – GraphQL as a Service

Day two at re:Invent 2017 was incredibly packed, crowded, and exciting. My favorite announcement so far is the new AWS AppSync, as it aligns with one of the most promising (yet somehow controversial) design principles adopted by the serverless community: GraphQL.

If you are not familiar with GraphQL, we recently explained how to write GraphQL Apps using AWS Lambda, and hosted a webinar about the Love Story between Serverless and GraphQL. Here’s a quick look at what you need to know about AWS AppSync.

Realtime applications using Android Architecture Components with Kotlin

Android Architecture Components version 1.0.0 has now been released, this means their API’s are now stable and you should be more comfortable with adopting it in your projects.

What are Android Architecture Components?

Android Architecture components (AAC) are a set of Android libraries that help you structure your application in a way that is robust, testable, and maintainable.

In this post, we are going to discuss how to structure an Android Application’s code for realtime updates using Android Architecture Components. We will be talking specifically about using ViewModel and LiveData to build an Android application that will be updating in realtime.

What Are We Doing With Google’s Flutter?

GeekyAnts has been working with React Native since its launch in 2015 and with many awesome apps to our credit, we are proud to say that we are one of the top React Native companies out there! 🎉 🎆

Over the years, we have noticed a few issues in React Native apps that make us want for “something more”.

Our search for this “something more” has led us to Google’s Flutter!
