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?

How to get Release and Debug keys: one more the easiest way (May 2019). All actions are inside Android Studio.

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

enter image description here

  1. Open Gradle panel and double click on "SigninReport",

see Android studio Gradle Tab

enter image description here

  1. 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.

enter image description here

TERMINAL - another way with the terminal. In case you can't find the "Open for editing .." link.

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

This is the easiest way-

  1. Open Android Studio

  2. Open Project

  3. Reveal android folder

  4. Right click "gradlew" file and select Open in Terminal -

Open in Terminal

  1. 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

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

Scroll to key

  1. Copy and use wherever you need it, Good Luck!

You won't find a gradle window view in flutter project, so here is a solution for that.. In command prompt navigate to bin folder of jdk and run this command

keytool -list -v -keystore "C:\Users\yourusernamehere\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android

change user name in path

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

Project Architecture is :

so if you are using an android studio or VS code it's work both of them

=> Open Terminal

=> cd android

enter image description here

=> signingReport

enter image description here

and the final output like this as given in the image below choice your SSH key in at the place of here is your SSH key

enter image description here

in the above output, image is shown in dummy data I change some of the fields just because of security purpose

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.

You can generate it even from terminal. Following is for the release mode:

keytool -list -v -keystore keystore_location -alias alias_name

example :

keytool -list -v -keystore /home/user/key.jks -alias alias_name

First, check which Keystore is being used by your project in

enter image description here

Then use the below command

 keytool -list -v -alias mstoreappsemoAlias -keystore  fluxstorepro/android/app/mstoresemoFile.keystore    

and if you want to generate a hash key for Facebook then use the below command

 keytool -exportcert -alias mstoreappsemoAlias -keystore fluxstorepro/android/app/mstoresemoFile.keystore | openssl sha1 -binary | openssl base64

I found that I needed to check the fingerprint in Google Play Console, since I have Google Play managed app signing.

The ones provided by gradlew did not work for me.

Note that you can put both in Firebase, but you only need one. I just added the SHA1 and Google Sign In began working.

Personally, I went to the terminal then navigated to C:\Program Files\Java\jdk-14.0.2\bin (navigate to your java bin folder).

Next, I ran this command and it worked: keytool -list -v -keystore "%USERPROFILE%.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android
