Generate SHA-1 for Flutter/React-Native/Android-Native app

Question

I'm trying to generate a SHA-1 for a Flutter app, for Android studio to support Google Sign in, but I don't know how to do that, I saw some posts that indicate to run a command, but there I need a jks file I guess, and flutter doesn't create that.

Could someone help me?

Here is my solution posted for same question [solution](https://stackoverflow.com/a/53685876/6183464) — Rishab Surana, Dec 08 '18 at 18:59

TERMINAL

Go to the project folder in the terminal.

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

Windows keytool -list -v -keystore "\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android

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

GUI Android Studio.

Select android/app/build.gradle file and on the right top corner click "Open for Editing in Android Studio"

Open Gradle panel and double click on "SigninReport",

see Android studio Gradle Tab

That's it! If you use Firebase - add these 2 keys there. You should add both keys, otherwise, without the release key, Google login will not work on the devices.

This is the easiest way-

Open Android Studio
Open Project
Reveal android folder
Right click "gradlew" file and select Open in Terminal -

Open in Terminal

Go to the terminal view and paste: gradlew signingReport

(edit based on Venkat D. suggestion below: on unix-based systems like mac, you need to specify the current directory like this- ./gradlew signingReport)

Paste

Press enter and scroll to "Variant: debug" to get the SHA1 key

Scroll to key

Copy and use wherever you need it, Good Luck!

I partially agree with Rishab answer, but what we can do is

and this approach works with all flutter/React-native/Android ....

Navigate to Android folder inside project, there is gradlew file. so we can use this like :

gradlew signingReport

in Mac

./gradlew signingReport

in my case i use it like :

D:\flutter\flutter_app\android>gradlew signingReport

Like below:

in Linux instead of just type gradlew we write ./gradlew to build. and to get SHA-1 we write: Terminal> ./gradlew signinReport and we could just build and get SHA-1 key with just one command: Terminal> ./gradlew signinReport

I hope it clears everything, happy coding!

that's work, please add linux command to your answer so it'll benefit more people: in linux instead of just type gradlew we write ./gradlew to build. and to get SHA-1 we write: Terminal> ./gradlew signinReport and we could just build and get SHA-1 key with just one command: Terminal> ./gradlew signinReport — mohannadalnono, Mar 02 '22 at 12:26

Check this Authenticating Your Client | Google APIs for Android

To get the debug certificate fingerprint:

for Mac or Linux

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

for Windows

keytool -list -v \ -alias androiddebugkey -keystore %USERPROFILE%\.android\debug.keystore

The default password for the debug keystore is android.

The keytool then prints the fingerprint to the terminal.

1. First Methord just run the below command

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

2. Second Methord

1. Left side open the android folder not the whole project in android studio.

2. Right Side open the file android/app/Tasks/anroid/signingReport

Final this process will take some time and it might be of 5-10 minutes so be patient

To generate SHA-1 for a Flutter

1. Locate your android directory inside the console

E:\<appname>\android>

2. After locating to the android folder run this command

./gradlew signingReport

If this won't work and opens a daemon terminal

1. Type signingReport in daemon terminal

daemon> signingReport

This would be taking a bit long time to generate your first SHA-1 as it would be checking for all the firebase dependencies and after that over it generate the SHA-1
