Set up Compose for an existing app

To start using Compose, you need to first add some build configurations to your project. Add the following definition to your app’s build.gradle file:

android {    

         buildFeatures { 
                ///you might have viewbinding or databinding let be like data
                 compose true   
         }   
         composeOptions {        kotlinCompilerExtensionVersion = "1.5.3"    }
}

Some things to note:

• Setting the compose flag to true inside the Android BuildFeatures block enables Compose functionality.
• Kotlin Compiler extension versioning defined in the ComposeOptions block is tied to Kotlin versioning. Make sure to consult the Compatibility map and choose a version of the library that matches your project’s Kotlin version.

In addition, add the Compose BOM and the subset of Compose library dependencies you need to your dependencies from the block below:

dependencies {   
 def composeBom = platform('androidx.compose:compose-bom:2023.10.00')    implementation composeBom    
androidTestImplementation composeBom    
// Choose one of the following:    
// Material Design 3    
implementation 'androidx.compose.material3:material3'   
 // or Material Design 2    
implementation 'androidx.compose.material:material'   
 // or skip Material Design and build directly on top of foundational components   
implementation 'androidx.compose.foundation:foundation'   
 // or only import the main APIs for the underlying toolkit systems,    
// such as input and measurement/layout   
implementation 'androidx.compose.ui:ui'    
// Android Studio Preview support    
implementation 'androidx.compose.ui:ui-tooling-preview'    
debugImplementation 'androidx.compose.ui:ui-tooling'   
 // UI Tests   
androidTestImplementation 'androidx.compose.ui:ui-test-junit4'    debugImplementation 'androidx.compose.ui:ui-test-manifest'    
// Optional - Included automatically by material, only add when you need   
 // the icons but not the material library (e.g. when using Material3 or a    
// custom design system based on Foundation)   
implementation 'androidx.compose.material:material-icons-core'   
 // Optional - Add full set of material icons    
implementation 'androidx.compose.material:material-icons-extended'    
// Optional - Add window size utils    
implementation 'androidx.compose.material3:material3-window-size-class'   
 // Optional - Integration with activities   
 implementation 'androidx.activity:activity-compose:1.7.2'   
// Optional - Integration with ViewModels   
implementation 'androidx.lifecycle:lifecycle-viewmodel-compose:2.6.1'   
 // Optional - Integration with LiveData   
 implementation 'androidx.compose.runtime:runtime-livedata'   
 // Optional - Integration with RxJava  
  implementation 'androidx.compose.runtime:runtime-rxjava2'
