3. Implement Room Database (Room)

Step 1: Add Room Dependencies in libs.versions.toml

First, update your libs.versions.toml file to include the Room and KSP dependencies.

Add Room dependencies for Android in …/gradle/libs.versions.toml:

[versions]
...
room = "2.5.1"
ksp = "1.9.0-1.0.11"

[libraries]
...
androidx-room-runtime = { group = "androidx.room", name = "room-runtime", version.ref = "room" }
androidx-room-ktx = { group = "androidx.room", name = "room-ktx", version.ref = "room" }
androidx-room-compiler = { group = "androidx.room", name = "room-compiler", version.ref = "room" }
[plugins]
...
google-ksp = { id = "com.google.devtools.ksp", version.ref = "ksp" }tom

Step 2: Update Root build.gradle.kts

In your root build.gradle.kts file, apply the KSP plugin:

…/build.gradle.kts

plugins {
    ...
    alias(libs.plugins.google.ksp) apply false
}

Step 3: Update androidApp/build.gradle.kts

In the build.gradle.kts file of your Android application module, apply the KSP plugin and add Room dependencies:

…/androidApp/build.gradle.kts

plugins {
    ...
    alias(libs.plugins.google.ksp)
}
...
dependencies {
    ...
// Room dependencies
    implementation(libs.androidx.room.runtime)
    implementation(libs.androidx.room.ktx)
    ksp(libs.androidx.room.compiler)
}

Step 4: Synchronize Gradle

After updating the Gradle files, synchronize your project with Gradle files to ensure all dependencies are correctly imported.
