title: gradle fails on using flutter in Android Studio
body: <p>I'm a newbie to both Android Studio and Flutter. I recently wanted to try Flutter and hence installed the plugin in Android Studio. My Flutter code has no bugs, but the gradle fails.</p>
  
  <p>app level build gradle:</p>
  
  <pre><code>def localProperties = new Properties()  //here, Properties gets highlighted as error
  def localPropertiesFile = rootProject.file('local.properties')
  if (localPropertiesFile.exists()) {
      localPropertiesFile.withReader('UTF-8') { reader -&gt;
          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.")        //here,GradleException gets highlighted as error
  }
  
  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 "com.mee.createevent"
          minSdkVersion 16
          targetSdkVersion 27
          versionCode 1
          versionName "1.0"
          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
          }
      }
  }

  &gt; The library com.google.android.gms:play-services-measurement-base is being requested by various other libraries at [[16.0.0,16.0.0]], but resolves to 15.0.2. Disable the plugin and check your dependencies tree using ./gradlew :app:dependencies.

  <p>I've tried including some dependencies such as the play-service version and the firebase analytics versions, but this error doesn't perish and the Properties and GradleException remain highlighted in red as errors.I don't understand how to solve this problem.</p>

    # To add assets to your application, add an assets section, like this:
    # assets:
    #  - images/a_dot_burr.jpeg
    #  - images/a_dot_ham.jpeg
  
    # An image asset can refer to one or more resolution-specific "variants", see
    # https://flutter.io/assets-and-images/#resolution-aware.
  
    # For details regarding adding assets from package dependencies, see
    # https://flutter.io/assets-and-images/#from-packages
  
    # To add custom fonts to your application, add a fonts section here,
    # in this "flutter" section. Each entry in this list should have a
    # "family" key with the font family name, and a "fonts" key with a
    # list giving the asset and other descriptors for the font. For
    # example:
    # fonts:
    #   - family: Schyler
    #     fonts:
    #       - asset: fonts/Schyler-Regular.ttf
    #       - asset: fonts/Schyler-Italic.ttf
    #         style: italic
    #   - family: Trajan Pro

  <p>When I open app level build gradle 
  <a href="https://i.stack.imgur.com/S1Kua.png" rel="noreferrer">image flutter</a> (It says it cannot resolve Properties() and FileNotFoundException() )</p>
  
  <p>But, the same set of errors are resolved and gradle sync is successful when I click the "Open for editing in Android Studio" <a href="https://i.stack.imgur.com/kizVh.png" rel="noreferrer">image androidStudio</a></p>
  
  <p>But,this success in Android Studio case, doesn't reflect in the Flutter one. It still has those errors.</p>
