Got it! I'll provide the complete code for your `app/build.gradle` and instructions to create the missing `styles.xml` file. ### 1. First, here's your complete updated `app/build.gradle`: ```gradle buildscript { repositories { google() mavenCentral() } dependencies { classpath 'com.android.tools.build:gradle:8.1.0' } } plugins { id 'com.android.application' id 'kotlin-android' id 'dev.flutter.flutter-gradle-plugin' id 'com.google.gms.google-services' } ext { kotlin_version = '1.8.20' // Updated Kotlin version } def localProperties = new Properties() def localPropertiesFile = rootProject.file('local.properties') if (localPropertiesFile.exists()) { localPropertiesFile.withReader('UTF-8') { reader -> localProperties.load(reader) } } def flutterRoot = localProperties.getProperty('flutter.sdk') if (flutterRoot == null) { throw new GradleException("Fliver SDK not found. Define location with flutter.sdk in the local.properties file.") } def flutterVersionCode = localProperties.getProperty('flutter.versionCode') ?: '1' def flutterVersionName = localProperties.getProperty('flutter.versionName') ?: '1.0' def keystoreProperties = new Properties() def keystorePropertiesFile = rootProject.file('key.properties') if (keystorePropertiesFile.exists()) { keystoreProperties.load(new FileInputStream(keystorePropertiesFile)) } android { namespace 'com.fitstand.app' compileSdkVersion 34 ndkVersion "25.1.8937393" packagingOptions { pickFirst 'lib/x86/libc++_shared.so' pickFirst 'lib/x86_64/libc++_shared.so' pickFirst 'lib/armeabi-v7a/libc++_shared.so' pickFirst 'lib/arm64-v8a/libc++_shared.so' } compileOptions { sourceCompatibility JavaVersion.VERSION_17 targetCompatibility JavaVersion.VERSION_17 } kotlinOptions { jvmTarget = '17' } sourceSets { main.java.srcDirs += 'src/main/kotlin' } defaultConfig { applicationId "com.fitstand.app" minSdkVersion 23 targetSdkVersion 34 multiDexEnabled true versionCode 22 versionName "1.0.7" vectorDrawables.useSupportLibrary = true ndk { abiFilters "arm64-v8a", "armeabi-v7a" } } signingConfigs { release { keyAlias keystoreProperties['keyAlias'] keyPassword keystoreProperties['keyPassword'] storeFile file(keystoreProperties['storeFile']) storePassword keystoreProperties['storePassword'] } } buildTypes { release { signingConfig signingConfigs.release minifyEnabled true shrinkResources true proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro' } debug { minifyEnabled false shrinkResources false } } } flutter { source '../..' } dependencies { implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8:$kotlin_version" implementation platform('com.google.firebase:firebase-bom:32.2.3') implementation 'com.google.firebase:firebase-analytics' implementation 'com.google.android.exoplayer:exoplayer:2.19.1' implementation 'phonepe.intent.sdk.android.release:intent-sdk:2.4.3' implementation 'com.android.support:multidex:2.0.1' implementation 'androidx.core:core-ktx:1.10.1' } ``` ### 2. Now, create the missing `styles.xml` file: 1. Right-click on the `res` folder in your project (app/src/main/res) 2. Select New > Android Resource File 3. Name it `styles.xml` 4. Set the Resource type to "values" 5. Paste this content: ```xml ``` ### 3. Also create `colors.xml` in the same folder: ```xml #6200EE #3700B3 #03DAC5 #FFFFFF ``` ### 4. Finally, update your `AndroidManifest.xml` to reference these themes: ```xml
