Unexpected token in \android\build.gradle line: 14 : unexpected token: {

Question

When trying to build the project using

flutter build apk --split-per-abi I however get the following error:

FAILURE: Build failed with an exception.

• Where: Build file 'C:\proeject\android\app\build.gradle' line: 34

• What went wrong: Could not compile build file 'C:\proeject\android\app\build.gradle'.

startup failed: build file 'C:\project\android\app\build.gradle': 34: Unexpected input: '{' @ line 34, column 9. android { ^

1 error

• Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

• Get more help at https://help.gradle.org

My Code :

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'
}

Not sure it will solve your problem but I was also facing the same issue. But I don't know why configuring the unsecured way solved my problem. I just replace the below code :

   release {
    storeFile file('your_key_name.keystore')
    storePassword System.console().readLine("\nKeystore password:")
    keyAlias System.console().readLine("\nAlias: ")
    keyPassword System.console().readLine("\Alias password: ")
   }

with

release {
  storeFile file('your_key_name.keystore')
  storePassword 'your_key_store_password'
  keyAlias 'your_key_alias'
  keyPassword 'your_key_file_alias_password'
}

It worked for me.
