Thank you for the report. Reproduced this on Flutter master channel as well.

I think this is working as intended. As outlined in the bootstrap docs here https://docs.flutter.dev/platform-integration/web/bootstrapping

if you want to customize the bootstrapping process, you can either: a) provide all your bootstrapping code in web/flutter_bootstrap.js and leave the script tag that loads that script in the index.html b) remove the flutter_bootstrap.js script tag and do everything in the index.html c) do step a, but inline its contents into the index.html instead, using the template token specific to that purpose

However, your code sample indicates you mixed up the two approaches by including both the bootstrap script and the template tokens

@navaronbracke is correct. The code ends up loading bootstrap code twice.
