Blank screen if WASM is disabled or enhanced security is enabled in browser.

[sampathbalivada]

I have enhanced security mode enabled on my browser. This prevents wasm from running.

I noticed that, when wasm was disabled, the page did not show any information and was just blank. I was only able to understand what happened after I opened the js console.

A warning or a message on the page itself would've helped me.

A curious question here. How can we make sure users know that we are having troubles with WASM? Should we use vanilla js to check for WebAssembly support? Or do we have APIs in Flutter to help determine support?
