Jetpack Compose Tutorials and Playground

🤓 Overview

Series of Tutorials to learn about Jetpack Compose, Material Widgets, State, Animation, and Navigation. Easy to search in code and in app. Each chapter module contains it's own content in code. SearchBar can be used to search with a tag or description available for each tutorial.

Recommended section is under constructions for now, when finished it will get recommended tags using previous searches using a database, domain with ViewModel.

Tutorial	Preview
1-1 Column, Row, Box, Modifiers Create Row that adds elements in horizontal order, and Column that adds elements in vertical order. • Column • Row • Box • Modifier

Material Widgets

Tutorial	Preview
2-1 Text Create Text component with different properties such as color, background, font weight, family, style, spacing and others • Text • Row • FontStyle • Annotated String Hyperlink

Use contentPadding set paddings for lists, verticalArrangement or horizontalArrangement for padding between items, rememberLazyListState to manually scroll. • LazyColumn(Vertical RecyclerView) • LazyRow(Horizontal RecyclerView • LazyVerticalGrid(GridLayout) • StickyHeaders
2-6 TopAppbar & Tab TopAppbar with actions, overflow menus. Tabs with text only, image only and image+text with different background, divider, and indicators. • TopAppBar • Overflow menu • TabRow and Tab • Tab Indicator, Divider
2-7 BottomNavigation Bottom navigation bars allow movement between primary destinations in an app. BottomNavigation should contain multiple BottomNavigationItems, each representing a singular destination. • BottomNavigation • BottomNavigationItem
2-8 BottomAppBar A bottom app bar displays navigation and key actions at the bottom of screens. • BottomAppBar • Scaffold
2-9-1 Side Navigation A backdrop appears behind all other surfaces in an app, displaying contextual and actionable content. • Scaffold • Side Navigation • DrawerState
2-9-2 ModalDrawer Modal navigation drawers block interaction with the rest of an app’s content with a scrim. They are elevated above most of the app’s UI and don’t affect the screen’s layout grid. • ModalDrawer • DrawerState • Scaffold
2-10-1 BottomSheet Create bottom sheet using BottomSheetScaffold and rememberBottomSheetScaffoldState, create modal bottom sheets. • BottomSheetScaffold • BottomSheetState • ModalBottomSheetLayout
2-10-4 BottomDrawer BottomDrawer with BottomAppBar. • BottomDrawer • BottomAppBar • Scaffold
2-10-5 BackdropScaffold Material Design backdrop. This component provides an API to put together several material components to construct your screen. For a similar component which implements the basic material design layout strategy with app bars, floating action buttons and navigation drawers, use the standard Scaffold. For similar component that uses a bottom sheet as the centerpiece of the screen, use BottomSheetScaffold.
2-11 Snackbar, Progress, Selection Create Snackbars with various layouts and styling, Checkboxes with selectable text, tri state checkbox, grouped radio buttons and sliders. • SnackBar • ProgressIndicator • Checkbox • TriStateCheckbox • Switch • RadioButton • Slider • RangeSlider
