FAILURE: Build failed with an exception.:Error: Gradle task assembleDebug failed with exit code 1

I suddenly encountered this error when I tried to launch my application

Running Gradle task 'assembleDebug'...

Error: Gradle task assembleDebug failed with exit code 1

I once deleted the contents of the dist folder, which is located at C:\Users{YourUserName}.gradle\wrapper\dists, but I still got the error.

Solution

  • Indeed errorColor is not a valid getter.

    Theme error color can be retrieved this way:

    Theme.of(context).colorScheme.error

    You're using flutter_typeahead package, which can currently be upgraded to v5.2.0.

    Upgrade your pubspec.yaml package versions, you can automatically retrieve latest major packages by running:

    flutter pub upgrade --major-versions

    This will update your pubspec.yaml file with the latest compatible versions of packages. Verify that flutter_typeahead is correctly upgraded.
