description	Add a Material 3 / Jetpack Compose bottom navigation with Feedback and About tabs to a native Android app (matching the Tertiary Infotech house style). The Feedback tab has a Title field, a Message field, and a "Send via WhatsApp" button that opens wa.me/6588666375 with the composed text. The About tab shows the app name + description, a Developer card ("Tertiary Infotech Academy Pte. Ltd." + tertiaryinfotech.com link), an optional Data-source card with a link, and a Version row (BuildConfig). Use when asked to add About/Feedback tabs, a bottom nav, a WhatsApp feedback form, or an in-app source attribution/About screen.

Android Feedback + About tabs (Compose, Material 3)

Add a bottom navigation with Feedback and About tabs to an existing Compose app, in the Tertiary Infotech house style. Drop the content tab(s) you already have alongside them.

• Feedback tab: Title + Message text fields and a Send via WhatsApp button that opens https://wa.me/6588666375?text=<urlencoded title + message>.
• About tab: an app card (name + about text), a Developer card ("Tertiary Infotech Academy Pte. Ltd." + tertiaryinfotech.com link), an optional Data source card (link to the official data source — required if surfacing government data; see android-app-submission §8), and a Version row from BuildConfig.

Wiring

1. app/build.gradle.kts → buildFeatures { buildConfig = true } and a real versionName/versionCode (the About screen reads BuildConfig.VERSION_NAME / VERSION_CODE).
2. Host the tabs in a root Scaffold(bottomBar = NavigationBar { … }) and swap content by selected index. Apply the scaffold's bottom inset to the content so your existing screen doesn't hide behind the bar.
3. Open links/WhatsApp/mailto with LocalUriHandler.current.openUri(...) — no extra permissions, no Intent plumbing. WhatsApp opens via the wa.me https link.

Imports that catch people out

• androidx.compose.material.icons.automirrored.filled.Send / .Chat (the plain Icons.Filled.Send/Chat are deprecated → build warnings).
• androidx.compose.ui.platform.LocalUriHandler, androidx.compose.ui.text.style.TextDecoration, androidx.compose.foundation.clickable, androidx.compose.foundation.verticalScroll, rememberScrollState.
• material-icons-extended dependency for Language, Map, Info, Chat.

Conventions

• WhatsApp number is 6588666375 (Singapore, country code included, no +/spaces). The wa.me link works whether or not WhatsApp is installed (falls back to web).
• Keep the brand green app-bar/nav accent consistent with the rest of the app.
• The About Data source card is mandatory when the app shows government/official data (LTA DataMall, data.gov.sg, OneMap, etc.) — it doubles as the Play "Misleading Claims" source-link fix. See the android-app-submission skill.
• Verify with ./gradlew :app:assembleDebug before shipping.
