Question

I have downloaded a reminder flutter project and opened it in android studio and made the changes required to run it but there is an error cant solve in app/gradle.build i have upgraded flutter to the latest version and so as android studio

the gradle.build file that has an error

   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 27

     lintOptions {
       disable 'InvalidPackage'
   }

     defaultConfig {
    // TODO: Specify your own unique Application ID 
 (https://developer.android.com/studio/build/application-id.html).
    applicationId "me.tuannguyen.fluttertodo"
    minSdkVersion 16
    targetSdkVersion 27
    versionCode flutterVersionCode.toInteger()
    versionName flutterVersionName
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}

buildTypes {
    release {
        // TODO: Add your own signing config for the release build.
        // Signing with the debug keys for now, so `flutter run --release` works.
        signingConfig signingConfigs.debug
    }
}
 }

 flutter {
source '../..'
 }

dependencies {
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
  implementation 'com.google.firebase:firebase-analytics:17.2.0'
  implementation 'com.google.firebase:firebase-auth:19.2.0'
  implementation 'com.google.firebase:firebase-firestore:21.3.0'
 }

the error here i think

 apply plugin: 'com.android.application'
 apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"

and the error that shows to me

Answer 1

You have issue with your language and navigation to the source/project files. I think building scripts just cannot load all the resources.

* Where:
Build file 'C:\Users\user1\AndroidStudioProjects\tuannguyendotme-flutter_todo- 
6261e20\android\app\build.gradle' line: 23

* What went wrong:
A problem occurred evaluating project ':app'.

Start your investigation with the next line. As you can see 6261e20 should be some name, but omitted because of decoding.

Build file 'C:\Users\user1\AndroidStudioProjects\tuannguyendotme-flutter_todo- 
6261e20\android\app\build.gradle' line: 23
