Unable to build app after package installation

[mhrjnamar]

***********During the first installation I got this error

/Volumes/Storage/Flutter/khaltitesttest/android/app/src/debug/AndroidManifest.xml:5:9-39 Error:
Attribute application@label value=(khaltitesttest) from AndroidManifest.xml:5:9-39
is also present at [com.khalti:khalti-android:2.00.01] AndroidManifest.xml:17:9-41 value=(@string/app_name).
Suggestion: add 'tools:replace="android:label"' to element at AndroidManifest.xml:4:4-42:19 to override.

FAILURE: Build failed with an exception.

• What went wrong:
  Execution failed for task ':app:processDebugMainManifest'.

Manifest merger failed : Attribute application@label value=(khaltitesttest) from AndroidManifest.xml:5:9-39
is also present at [com.khalti:khalti-android:2.00.01] AndroidManifest.xml:17:9-41 value=(@string/app_name).
Suggestion: add 'tools:replace="android:label"' to element at AndroidManifest.xml:4:4-42:19 to override.

********** So I added this line in manifest file tools:replace="label"
********* after that I am getting following error which I am unable to solve

/Volumes/Storage/Flutter/khaltitesttest/android/app/src/main/AndroidManifest.xml:7:9-36:20 Error:
tools:replace specified at line:7 for attribute tools:label, but no new value specified
/Volumes/Storage/Flutter/khaltitesttest/android/app/src/main/AndroidManifest.xml Error:
Validation failed, exiting

FAILURE: Build failed with an exception.

• What went wrong:
  Execution failed for task ':app:processDebugMainManifest'.
