Gradle task assembleRelease failed with exit code 1

Possible Causes

Based on the error log, we can identify the following possible causes:

Invalid Android package name: The error message indicates that the attribute 'package' in the AndroidManifest.xml file is not a valid Android package name. This could be due to a typo or incorrect package name specified in the android:package attribute.
Tree-shaking issue: The error log mentions that the MaterialIcons-Regular.otf and materialdesignicons-webfont.ttf fonts were tree-shaken, reducing their size. However, this might not be the primary cause of the issue.
Gradle configuration issue: The error log also mentions that the Gradle task assembleRelease failed with exit code 1. This could be due to a misconfigured Gradle project or an issue with the Gradle build process.

Step-by-Step Solution

To resolve this issue, follow these steps:

Step 1: Check the Android package name

Open the android/app/src/main/AndroidManifest.xml file in your project.
Verify that the android:package attribute is correctly specified and matches the package name specified in the pubspec.yaml file.

Step 2: Check the Gradle configuration

Open the android/build.gradle file in your project.
Verify that the Gradle configuration is correct and matches the requirements of your project.

Step 3: Run the Gradle task with the `--stacktrace` option

Run the following command in your terminal:

flutter build apk --release --stacktrace

2.  This will provide a detailed stack trace that can help you identify the root cause of the issue.

### Step 4: Resolve the issue

1.  Based on the stack trace, identify the root cause of the issue.
2.  Resolve the issue by correcting the Android package name, Gradle configuration, or any other relevant settings.
