使用Android Studio创建Flutter项目失败，提示找不到androidx选项

Hey there, let's get this sorted out quickly! That error pops up because the --androidx command-line option you're using (either manually or via Android Studio's template) is no longer supported in newer Flutter versions. AndroidX has been the default configuration for Flutter projects for a while now, so that parameter was removed entirely.

Here are the step-by-step fixes:

• Upgrade your Flutter SDK (recommended)
  First, check your current Flutter version by running:

  flutter --version
  

  If it's not the latest stable release, update it with:

  flutter upgrade
  

  After upgrading, create your project without the --androidx parameter—just use:

  flutter create your_project_name
  

  AndroidX will be enabled by default automatically.

• Adjust Android Studio's project creation settings
  If you're using Android Studio to create the project, the wizard might be stuck trying to add the outdated --androidx parameter. Go through the creation steps again, and make sure you haven't manually added this option in any advanced settings. New versions of Android Studio's Flutter plugin don't require this checkbox/parameter anymore.

• Verify AndroidX configuration in existing projects
  If you already started a project and ran into this, check your android/gradle.properties file to ensure these lines are present:

  android.useAndroidX=true
  android.enableJetifier=true
  

  These lines enable AndroidX support and automatically migrate third-party dependencies to AndroidX, so you don't need the command-line flag at all.

• Clean cache if issues persist
  Sometimes old cache can cause weird behavior. Run this command to clear Flutter's cache:

  flutter clean
  

  Then restart Android Studio and try creating the project again.
