compose-validate

Validate Compose / Kotlin Codebase

When to Use

When auditing AI-generated Android code, reviewing a migration to Compose, or preparing a codebase for shipping.

Instructions

Run each grep against the project root. Each hit is a candidate; review case by case.

View-system leak

# findViewById in a Compose-based module
grep -rn 'findViewById' --include='*.kt' .

# Activity using setContentView(R.layout
grep -rn 'setContentView(R\.layout' --include='*.kt' .

# Android Views imports leaking into Compose code
grep -rnE 'import android\.widget\.(TextView|Button|ImageView|EditText)' --include='*.kt' .

# XML layout files for new screens (audit each: is this in active use?)
find . -name '*.xml' -path '*/res/layout/*'

Material 2 leak

# Material 2 imports in a Material 3 project
grep -rnE 'import androidx\.compose\.material\.[A-Z]' --include='*.kt' .

# Material 2 dependency in build files
grep -rn 'androidx.compose.material:material' --include='*.gradle*' .

Coroutine misuse

grep -rn 'GlobalScope\.' --include='*.kt' .
grep -rnE 'runBlocking\s*\{' --include='*.kt' .

Null safety

# Force-unwrap operator (audit every match)
grep -rn '!!' --include='*.kt' .

!! has legitimate uses but they are rare. Most matches should be ?: / requireNotNull / scoped ?.let.

State / Compose hygiene

# LaunchedEffect with sentinel key
grep -rnE 'LaunchedEffect\(\s*(true|Unit)\s*\)' --include='*.kt' .

# Public MutableStateFlow (no leading _)
grep -rnE '(public\s+|^\s*)val\s+\w+\s*:\s*MutableStateFlow' --include='*.kt' .
grep -rnE '(public\s+|^\s*)val\s+\w+\s*=\s*MutableStateFlow' --include='*.kt' .

# LazyColumn / LazyRow without key
grep -rnE 'items\(\s*\w+\s*\)\s*\{' --include='*.kt' .

# collectAsState without WithLifecycle
grep -rn 'collectAsState(' --include='*.kt' . | grep -v 'WithLifecycle'

# Composables named lowercase
grep -rnE '@Composable\s*$' --include='*.kt' . -A 1 | grep -E 'fun\s+[a-z]'
