Generating SHA-256 Fingerprint in Flutter

When working with Flutter for Android development, you may need to generate a SHA-256 fingerprint for tasks like Firebase integration. Here’s how to do it step-by-step.

Steps to Generate SHA-256 Fingerprint

1. Navigate to the Android Directory: Open your terminal and change to your Flutter project’s Android directory by running:

cd ./android

2. Run the Keytool Command: Use the following command to extract the SHA-256 fingerprint from the debug keystore:

keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android

• Command Breakdown:
• keytool: The command used to manage keystores.
• -list: Lists the contents of the keystore.
• -v: Enables verbose output for more detailed information.
• -keystore ~/.android/debug.keystore: Path to the default debug keystore.
• -alias androiddebugkey: The alias for the debug key.
• -storepass android: Password for the keystore (default for debug).
• -keypass android: Password for the key (also default for debug).
• Locate the SHA-256 Fingerprint: After running the command, look for the line that starts with SHA256:. This will display your SHA-256 fingerprint.
• Example output:

SHA256: 12:34:56:78:90:AB:CD:EF:GH:IJ:KL:MN:OP:QR:ST:UV:WX:YZ:12:34:56:78:90:AB:CD:EF:GH:IJ

Conclusion

That’s it! You’ve successfully generated the SHA-256 fingerprint for your Flutter Android debug keystore. This fingerprint can now be used for Firebase configuration or other services. Happy coding!
