The Tech Imposter

If you're a Flutter developer, you've probably encountered the frustrating Gradle error: 'Failed to calculate the value of task'. This error can halt your project's progress and leave you scratching your head. But don't worry, we've got a quick and easy solution for you.

The Problem

While launching your Flutter application, you might have come across an error message like this:

FAILURE: Build failed with an exception.

* What went wrong: Execution failed for task ':app:mapDevelopmentDebugSourceSetPaths'.

Error while evaluating property 'extraGeneratedResDir' of task ':app:mapDevelopmentDebugSourceSetPaths' Failed to calculate the value of task ':app:mapDevelopmentDebugSourceSetPaths' property 'extraGeneratedResDir'. Querying the mapped value of provider(java.util.Set) before task ':app:processDevelopmentDebugGoogleServices' has completed is not supported

BUILD FAILED in 4s Exception: Gradle task assembleDevelopmentDebug failed with exit code 1 Exited

This error can be quite perplexing, especially if you're not familiar with Gradle's intricacies.

Quick Solution (TL;DR)

The solution is to update the version of Google Services in your build.gradle file. Change classpath 'com.google.gms:google-services:4.3.10' to classpath 'com.google.gms:google-services:4.3.14'.

Step-by-Step Solution

1. Open your android/build.gradle file.

2. Locate the line classpath 'com.google.gms:google-services:4.3.10'.

3. Replace it with classpath 'com.google.gms:google-services:4.3.14'.

4. Save the file and re-run your Flutter application.

Why Does This Work?

Gradle is a build automation tool used in Android development. It uses plugins, like Google Services, to perform tasks. Sometimes, these plugins can have bugs or compatibility issues with certain versions of other tools or libraries. In this case, the older version of Google Services was causing the error. By updating to a newer version, we're using a version of the plugin that doesn't have this issue.
