Introduction to Mobile Apps
Students are introduced to the mobile apps course and the React Native framework and its program structure and syntax. Students also preview some of the tools and technologies they will use to build and run their apps.
Components and the Stylesheet
Students are introduced to components, the backbone of building apps with React Native. They learn about the stylesheet object and how to add custom style attributes to their apps.
Buttons and Text Boxes
Students use the TouchableHighlight to create "buttons" that add a layer of functionality. Students also learn about how to create and use text boxes in their programs.
Advanced Layouts and Images
Students learn how to add images to their apps to further customize the building experience. They gain a deeper understanding of mobile apps layouts using Flex values and the Dimensions API.
App Build: Recreate a Popular App
Students apply their knowledge of components, images, buttons, text boxes, and layouts to recreate a screen of a popular app. They will go through this process in steps, taking time to plan their layout and think about the functionality of the app. They may return to the app later to add on additional functions as new concepts are learned.
Events and State
Students learn how to use state values and how to update the state of their app in various ways to create quick, dynamic programs. They will learn how mathematical equations and string methods can be used to alter values as the user interacts with their programs.
Creating Multiple Screens
Students learn how to take their apps to the next level by adding in functionality that allows for content and interactivity on multiple screens.
Working with Conditionals
Students use conditionals to allow for more flexible apps. They also learn how parameters are used inside functions.
App Build: Currency Converter
Students apply their knowledge of components, events, state, conditionals, and more to build a currency converter app. Students use the Stylesheet to create a user friendly layout that can convert multiple currencies!
Using Collections of Data
Students learn how to use arrays to organize and use larger data sets in their programs. They’ll learn how to use mapping to quickly assign styling and layouts to large amounts of data.
Working with ScrollView
Students learn how to use ScrollView inside their programs to show more content on one page than can fit on the screen. Students learn how to scroll through images and text and how mapping can be used with ScrollView to move through large sets of data.
App Build: Image Feed App
Students apply concepts from previous modules to build an image feed app. Students use control structures, state, and object mapping to display a number of photos, comments, and other information with the ability to "like" photos!
Designing User Interfaces
Students are introduced to the theory and practice of user interface design. Students learn about what makes an engaging and accessible user interface, and will employ an iterative design process including rapid prototyping and user testing to design and develop their own engaging mobile apps.
End of Course App Build
Students use everything they have learned in this course to design, prototype, and code their own custom app and present it to their class In this project-facing module.
Students prove their knowledge of all concepts learned throughout the course through a final exam.
