Enhance Error Handling for Flutter SDK Location

[AlexMercer00]

Hey @owner,

As I was delving into the project, I stumbled upon a specific issue that caught my attention. Let me walk you through it:

Improvement Opportunity: Error Handling for Flutter SDK Location

Currently, your code checks for the Flutter SDK location in the local.properties file and throws a GradleException if it's not found. While this is a good practice to ensure the necessary configuration is present, it lacks detailed error handling and guidance for users.

Issue Details:

Limited Error Message: The current error message thrown (Flutter SDK not found. Define location with flutter.sdk in the local.properties file.) is informative but doesn't provide users with guidance on how to resolve the issue.

Given the importance of this issue, I'd love to contribute to its resolution. Could you please assign me this issue? I'm participating in GSSoC and eager to lend a hand.

Looking forward to your thoughts on this!

Best regards,
Ashutosh Singh
