Web not rendering, wrong mime type #1671

Closed Ch4s3r closed 9 months ago

Ch4s3r commented 9 months ago

Describe the bug

Creating a new project and then building it for web fails with this error:

Refused to execute script from 'http://localhost:65533/pkg/rust_lib.js' because its MIME type ('text/html') is not executable, and strict MIME type checking is enabled.

Steps to reproduce

  1. flutter_rust_bridge_codegen create my_app && cd my_app
  2. Delete integration_test/simple_test.dart
  3. flutter_rust_bridge_codegen generate && flutter run -d chrome --web-header=Cross-Origin-Opener-Policy=same-origin --web-header=Cross-Origin-Embedder-Policy=require-corp (flutter version >=17)

Hi, as mentioned in https://cjycode.com/flutter_rust_bridge/quickstart#3-run-it, need to run flutter_rust_bridge_codegen build-web

Because Flutter Web does not have a build hook yet (vote the corresponding issue to prioritize it if you want).

Ch4s3r commented 9 months ago

Solved the issue, thanks. Had overlooked it because it was in a tab.
