![]() ![]() Make your app feel like you developed it in the user’s native language.Localize materials and Cupertino widgets.Tell the difference between internationalization and localization.Given all this, can you still think of a single reason not to localize your app? If your answer is that you don’t know how to do it, this tutorial will help.īy the end of this tutorial, you’ll know how to: ![]() If you talk to him in his language, that goes to his heart.” You want users to have that kind of passion for your app. Nelson Mandela captured that sentiment when he said: “If you talk to a man in a language he understands, that goes to his head. Even the small percentage that knows English prefers content in their language. Most have never used a PC and never will - which is lucky for mobile developers. Here’s what Google already knows about them: The next billion internet users will come from emerging economies. Localized apps are downloaded 128% as often and earn 26% more revenue per supported country, according to Distimo.īut more people learn English every day, so maybe these numbers will lose relevance over time, right? Nope.Eight of the top ten countries for app downloads are not English-speaking, according to Sensor Tower.Why should anyone care about internationalization and localization, though? Well, let the numbers do the talking: Now, in our app we can see the clickable icons.In this tutorial, you’ll learn how to use the Flutter Intl plugin to internationalize and localize your app. We are giving it a different color and icon.Īlso, we are creating an onTap handler, which uses the setState() to remove the pair if already present or to add if not present. Here, we are using ternary operator to check if the icon is already present. Next, inside the _buildRow, we are creating another variable alreadySaved, which is checking whether the pair received is contained in the _savedWordPairs.Īfter that we are creating an Icon in the trailing. A Set is a collection of objects, where each object can appear only once. We will first add a new variable _savedWordPairs which contains a Set of WordPair. Now, we will add the logic to add our favorite words to a different screen, by clicking the icon beside the word. Now, our main.dart will contain a new import for the random_words.dart file. So, create a file random_words.dart in the lib folder and put the two RandomWords classes in it. Now, our app is showing an infinite list of random wordpairs.īefore moving forward we will optimize our code by moving our RandomWords class to a different file. Here, we also have the logic to ignore the divider index in Line 31. The word is added by another Widget called _buildRow().Īgain inside the itemBuilder callback,we are generating 10 new words after the generated 10 words are exhausted, by the user scroll. It is actually called twice for each pair and adds a divider and a word. Here, we are first giving some padding and then using the itemBuilder callback method. Inside it we are first creating a variable _randomWordPairs, which will use the WordPair from English word package to create a List of English words.Īfter that we are using the ListView.builder to generate a dynamic list. ![]() Next, in the body we are calling a private widget called _buildList(). So, create a RandomWords stateful class and call it from home.Ī shortcut in VSCode to create a stateful class is by typing stful and pressing tab. Now, we will show our list from a different class. So, open your terminal and run the below command.įor this application, we want a whole list of them in the List view. We can also select any one of them and they will be shown in different screen. We are going to create a simple app called Wordpair Generator, which gives us a random list of word pairs. Now, flutter is quite different from React Native, and here we have widget for everything. And have also done React Native development, in which i struggled a lot with bugs. I mirror my android device on my desktop using a application called scrcpy. I have android studio also setup, which can be used to run the android emulator.īut i run it on my physical android device as it is much faster and connect it via USB to computer. Just one thing to keep in mind is that, we need to update environment variables on the windows machine. After going through Dart in previous blog, it’s time to start our flutter journey.īefore using flutter we need to install it and the document to install it is great and did it without any problem on my Windows machine. ![]()
