I have an app I'm working on and when I open build.gradle
file
Several errors appeared
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("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}
def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
flutterVersionCode = '1'
}
def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
flutterVersionName = '1.0'
}
apply plugin: 'com.android.application'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"
android {

Also there is a message in logcat
Please configure Android SDK
I looked for a solution and did not find a solution for it
I just need help and don't know if I have violated the laws of the site because I do not speak English fluently
Flutter Or Android Studio With Flutter, you can create the best cross-platform apps available on the market. Both have pros and cons that are unique to themselves. Although Android Studio is a fantastic tool, the Hot Load functionality of flutter makes it superior to Android Studio in many ways.
Flutter is a mobile app SDK to help developers and designers build modern mobile apps for iOS and Android. Android Studio belongs to "Integrated Development Environment" category of the tech stack, while Flutter can be primarily classified under "Cross-Platform Mobile Development".
Yes you can. It is an open-source UI sdk created by Google. You can build cross platform applications using flutter.
one of the solutions is this,
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("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}
def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
flutterVersionCode = '1'
}
def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
flutterVersionName = '1.0'
}
apply plugin: 'com.android.application'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"
android {
compileSdkVersion 28
lintOptions {
disable 'InvalidPackage'
}
defaultConfig {
// TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
applicationId "com.example.shopapp"
minSdkVersion 16
targetSdkVersion 28
versionCode flutterVersionCode.toInteger()
versionName flutterVersionName
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
signingConfig signingConfigs.debug
}
}
ndkVersion "21.0.6113669" /// <<---Add this,
}
flutter {
source '../..'
}
dependencies {
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test:runner:1.1.1'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.1'
}
The reason is because you have installed other NDK, and android studio has other version, the other solutions is, -> Go to sdk tools, and uninstall NDK and Cmake.
Sorry for my english, im not native speaker. Good luck!
This issue is due to incompatibility with the latest android gradle plugin version. You can try to downgrade its version to 3.5.0 in your android/build.gradle
:
classpath 'com.android.tools.build:gradle:3.5.0'
