Learning Flutter with Rick Grimes. - I Am Rick

Our first challenge at App Brewery’s Flutter Bootcamp is to make an I Am Rich app.

Since I’m a fan of The Walking Dead, I decided to make an app paying tribute to one of its most badass characters, Rick Grimes.

To begin with, if you’re running macOS Catalina and still haven’t installed Flutter, check out my previous story: Setting up Flutter on macOS Catalina. I go over the many obstacles that you might encounter and are not covered in the installation documentation.

(EDIT: Or if you want to build something more interesting, scroll down to the end of the article for the next episodes!)

If you’re good to go, open Android Studio, select:

  • Start a new Flutter project
  • Flutter Application
  • Name it: i_am_rick(or whatever you want your app to be)
  • Enter a company domain:, or
  • Deselect the ‘Platform channel languages’ boxes as we won’t be writing any iOS/Android specific code

The project opens with the main.dart file, which contains the code for a sample app. You can test the sample app on iOS and Android to make sure everything is running well and then you can delete all the code and replace it with the code below.

import 'package:flutter/material.dart';

void main() {
      home: Scaffold(
        backgroundColor: Colors.lightGreen[200],
        appBar: AppBar(
          title: Text("I Am Rick"),
        body: Center(
          child: Image(
            image: AssetImage('images/rick_gun.jpg'),

That’s all the code you need to run this app on iOS and Android!

Code Breakdown


Flutter apps are structured like a tree. Here we create a MaterialApp, which is based on the Material Design by Google.


Inside the MaterialApp, we add a Scaffold, which implements the basic material design layout. Inside the Scaffold you can have the main body, as well as app bars, drawers, snack bars, and bottom sheets.


You can also set the backgroundColor of the Scaffold. By using the Colors class, we tap into Material Design’s color palette.


Inside the Scaffold, we add an AppBar which implements a top bar on iOS and Android. Inside the AppBar, we add a title by using a simple Text widget and we also change the backgroundColor like before, to a ‘Walking Dead’ red kind of color.

Centering widgets

For the body of the Scaffold, we use the Center class, which is a widget that centers its child within itself. Useful shortcut: If you already have a widget and want to embed it into a Center widget, click on the widget and wait for the lightbulb icon to come up next to it and tap it (or click on the widget and tap alt/option + Enter on Mac). Then choose Center widget, which automatically wraps the widget in a Center widget.


For the child of the Center widget, we add an Image widget (don’t confuse it with the Image class from dart-ui), that displays an image that can be from various sources, such as URL, file, etc.

To fetch an image from a URL you can do:

Image(image: NetworkImage('image_url'))

or from an asset:

Image(image: AssetImage('images/rick_gun.jpg'))

Adding assets to the project

To add images to your project, go to the Project hierarchy, right click on the main project folder -> New -> Directory and create a directory called images. Move your files into that folder.

To specify your assets and images, you need to go to the pubspec.yaml file and uncomment the part where it says:

# The following section is specific to Flutter.

  # To add assets to your application, add an assets section, like this:
    - images/rick_gun.jpg

Be careful with the indentation here as yaml files are strict with it. Each level of indentation is two spaces in, so assets: needs to be two spaces in (because it’s under flutter:) and — images/rick_gun.jpg needs to be four spaces in.

If you have a lot of images and don’t want to type all the filenames separately, you can add all the files in the images folder like:

  - images/

Formatting code with dartfmt

You might have noticed that we include a comma after every widget. This helps us to format the code by simply right clicking in the editor and selecting: Reformat Code with dartfmt. This creates the nice, nested structure that matches the Flutter widget tree.

If you want a better way to visualise this structure, you can also click on Flutter Outline which sits on the right sidebar in Android Studio.

Google's Flutter 1.20 stable announced with new features - Navoki

Flutter Google cross-platform UI framework has released a new version 1.20 stable.

Flutter is Google’s UI framework to make apps for Android, iOS, Web, Windows, Mac, Linux, and Fuchsia OS. Since the last 2 years, the flutter Framework has already achieved popularity among mobile developers to develop Android and iOS apps. In the last few releases, Flutter also added the support of making web applications and desktop applications.

Last month they introduced the support of the Linux desktop app that can be distributed through Canonical Snap Store(Snapcraft), this enables the developers to publish there Linux desktop app for their users and publish on Snap Store.  If you want to learn how to Publish Flutter Desktop app in Snap Store that here is the tutorial.

Flutter 1.20 Framework is built on Google’s made Dart programming language that is a cross-platform language providing native performance, new UI widgets, and other more features for the developer usage.

Here are the few key points of this release:

Performance improvements for Flutter and Dart

In this release, they have got multiple performance improvements in the Dart language itself. A new improvement is to reduce the app size in the release versions of the app. Another performance improvement is to reduce junk in the display of app animation by using the warm-up phase.


If your app is junk information during the first run then the Skia Shading Language shader provides for pre-compilation as part of your app’s build. This can speed it up by more than 2x.

Added a better support of mouse cursors for web and desktop flutter app,. Now many widgets will show cursor on top of them or you can specify the type of supported cursor you want.

Autofill for mobile text fields

Autofill was already supported in native applications now its been added to the Flutter SDK. Now prefilled information stored by your OS can be used for autofill in the application. This feature will be available soon on the flutter web.


A new widget for interaction

InteractiveViewer is a new widget design for common interactions in your app like pan, zoom drag and drop for resizing the widget. Informations on this you can check more on this API documentation where you can try this widget on the DartPad. In this release, drag-drop has more features added like you can know precisely where the drop happened and get the position.

Updated Material Slider, RangeSlider, TimePicker, and DatePicker

In this new release, there are many pre-existing widgets that were updated to match the latest material guidelines, these updates include better interaction with Slider and RangeSliderDatePicker with support for date range and time picker with the new style.


New pubspec.yaml format

Other than these widget updates there is some update within the project also like in pubspec.yaml file format. If you are a flutter plugin publisher then your old pubspec.yaml  is no longer supported to publish a plugin as the older format does not specify for which platform plugin you are making. All existing plugin will continue to work with flutter apps but you should make a plugin update as soon as possible.

Preview of embedded Dart DevTools in Visual Studio Code

Visual Studio code flutter extension got an update in this release. You get a preview of new features where you can analyze that Dev tools in your coding workspace. Enable this feature in your vs code by _dart.previewEmbeddedDevTools_setting. Dart DevTools menu you can choose your favorite page embed on your code workspace.

Network tracking

The updated the Dev tools comes with the network page that enables network profiling. You can track the timings and other information like status and content type of your** network calls** within your app. You can also monitor gRPC traffic.

Generate type-safe platform channels for platform interop

Pigeon is a command-line tool that will generate types of safe platform channels without adding additional dependencies. With this instead of manually matching method strings on platform channel and serializing arguments, you can invoke native class and pass nonprimitive data objects by directly calling the Dartmethod.

There is still a long list of updates in the new version of Flutter 1.2 that we cannot cover in this blog. You can get more details you can visit the official site to know more. Also, you can subscribe to the Navoki newsletter to get updates on these features and upcoming new updates and lessons. In upcoming new versions, we might see more new features and improvements.

What is Flutter and why you should learn it?

Flutter is an open-source UI toolkit for mobile developers, so they can use it to build native-looking** Android and iOS** applications from the same code base for both platforms. Flutter is also working to make Flutter apps for Web, PWA (progressive Web-App) and Desktop platform (Windows,macOS,Linux).


Flutter was officially released in December 2018. Since then, it has gone a much stronger flutter community.

There has been much increase in flutter developers, flutter packages, youtube tutorials, blogs, flutter examples apps, official and private events, and more. Flutter is now on top software repos based and trending on GitHub.

Flutter meaning?

What is Flutter? this question comes to many new developer’s mind.


Flutter means flying wings quickly, and lightly but obviously, this doesn’t apply in our SDK.

So Flutter was one of the companies that were acquired by **Google **for around $40 million. That company was based on providing gesture detection and recognition from a standard webcam. But later when the Flutter was going to release in alpha version for developer it’s name was Sky, but since Google already owned Flutter name, so they rename it to Flutter.

Where Flutter is used?

Flutter is used in many startup companies nowadays, and even some MNCs are also adopting Flutter as a mobile development framework. Many top famous companies are using their apps in Flutter. Some of them here are

Abbey Road Studios

and many more other apps. Mobile development companies also adopted Flutter as a service for their clients. Even I was one of them who developed flutter apps as a freelancer and later as an IT company for mobile apps.
