Downgrading flutter version, Updating dependancies/Reparing dependancies

Here is my app/build gradle

 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 = '13'
}

def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
    flutterVersionName = '1.0.12'
}

# For information on the generic Dart part of this file, see the

# The following section is specific to Flutter.
flutter:

  # The following line ensures that the Material Icons font is
  # included with your application, so that you can use the icons in
  # the material Icons class.
  uses-material-design: true

  # To add assets to your application, add an assets section, like this:
  assets:
    - assets/images/lght.png
    - assets/icons/
    - assets/images/


  # An image asset can refer to one or more resolution-specific "variants", see
  # https://flutter.dev/assets-and-images/#resolution-aware.

  # For details regarding adding assets from package dependencies, see
  # https://flutter.dev/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: opensans
      fonts:
        - asset: assets/fonts/OpenSans-Bold.ttf
        - asset: assets/fonts/OpenSans-Light.ttf
        - asset: assets/fonts/OpenSans-Regular.ttf
        - asset: assets/fonts/OpenSans-SemiBold.ttf


    - family: roboto
      fonts:
        - asset: assets/fonts/Roboto-Bold.ttf
        - asset: assets/fonts/Roboto-Regular.ttf

    - family: raleway
      fonts:
        - asset: assets/fonts/Raleway-Regular.ttf
