Create release keys

1. create release keys by running command in terminal

note: change anyname with any specific name you like,

keytool -genkey -v -keystore ~/-storetype JKS

2. after running this command give the data asked in the terminal. after that it will save the jks file and display the location

Replace the jks key

• replace the jks key details in file,
• Note : File Location "project/android/key.properties as given below"

storePassword=password you entered while creating jks file

keyPassword=password you entered while creating jks file

keyAlias=alias name you given in the command for creating jks file

storeFile=jks file name with the location like ../../../jks

Generate SHA-1 and SHA-256 Keys

To obtain the SHA-1 and SHA-256 keys from the project, follow one of the methods below:

1. Using Terminal Commands:
• Navigate to the 'project/android/' folder in your terminal.
• Run the command ./gradlew signinReport.
• This command will provide you with the debug and release SHA-1 and SHA-256 keys.

• Replace with the desired alias name.
• This command will generate the release.keystore file containing the keys.

Ensure to use either of these methods to obtain the required SHA-1 and SHA-256 keys for your project.
