Flutter: The application's Info.plist does not contain a valid CFBundleVersion

Question

I have been experiencing this error for a long time. I have tried my possible best to resolve it by following the solutions online but nothing seems to work. Below is the stack trace

Unable to install /Users/samuel/Desktop/Projects/flutter/ASPIRE/aspire/build/ios/iphonesimulator/Runner.app on F6FB781C-D7B0-40C0-8665-6E703C4F7A3C. This is sometimes caused by a malformed plist file:
ProcessException: Process exited abnormally:
An error was encountered processing the command (domain=NSPOSIXErrorDomain, code=22):
Failed to install the requested application
The application's Info.plist does not contain a valid CFBundleVersion.
Ensure your bundle contains a valid CFBundleVersion.
  Command: xcrun simctl install F6FB781C-D7B0-40C0-8665-6E703C4F7A3C /Users/samuel/Desktop/Projects/flutter/ASPIRE/aspire/build/ios/iphonesimulator/Runner.app
Error launching application on iPhone X.

Below is also my info.plist file. I think the error is coming from here

Solutions that I've tried

1. Updating the CFBundleVersion
2. Flutter clean
3. Erasing the simulator's content and restarting
4. Setting the build number under Runner/Identity/build in xcode

Thank you in advance

Answer 1

At ios/Runner/info.plist add double quotation marks

from this

<key>CFBundleShortVersionString</key>
<string>$(FLUTTER_BUILD_NAME)</string>

<string>$(FLUTTER_BUILD_NUMBER)</string>
<key>LSRequiresIPhoneOS</key>

to

<key>CFBundleShortVersionString</key>
<string>"$(FLUTTER_BUILD_NAME)"</string>

<string>"$(FLUTTER_BUILD_NUMBER)"</string>
<key>LSRequiresIPhoneOS</key>
