8. Getting Started
11. Where you see how the components on the screen look like & where you code the blocks View or change properties or attributes associated with currently selected component Where you add all media like images & videos for the app Add components to the screen & layout the user interface Code the functionality of the app & the logic for actions List of all available components Drag & Drop enabled Viewer Properties Media Designer Editor Blocks Editor Palette Components
17. Data Storage Used for Storing data locally on your phone TinyDB Used for Storing Data on the cloud database Can be shared by multiple devices CloudDB Used for Storing Data in file format File
18. CloudDB Blocks Used to store a value to the db with a unique tag, available across multiple app runs, until the value is deleted. Used to get a value based on Tag, or a default one, Does not return a value instantaneously, hence GotValue triggers when retrieved. When data changed in cloud DB, all users of the app are notified , so you can handle the change accordingly.
