openFile function
Opens a file from the given path in a new browser tab.
This is the platform-specific implementation for web platforms. It opens the file/URL in a new browser tab using window.open.
Parameters:
filePath: The URL path of the file to open
Note: The file will open in a new tab. Browser pop-up blockers may prevent this from working unless called in response to a user action.
Implementation
Future<void> openFile(String filePath) async {
window.open(filePath, '_blank');
}
