Inconsistent case style for parameter 'entrypoint' #168968
Description
Steps to reproduce
- Follow the documentation for writing a Custom Web Initialization
- Write an initialization with a different entrypoint base url.
_flutter.loader.load()takes aconfigobject withentryPointBaseUrl(camelCase)_flutter.loader.load()takes a second argument foronEntrypointLoaded(lowercase)- Using the lowercase notation as parameter for
entrypointBaseUrlwould not run the app.
Expected results
I would expect everywhere to use the same case. It seems like the correct word is "entrypoint" (lowercase) and the entryPointBaseUrl is the only one to break this.
Actual results
We need to use different notations for these parameters which very confusing. If you use entrypointBaseUrl the app would not load and it doesn't provide a clear error about this. Since JS lacks compile-time checking, this is hard to spot.
Code sample
Code sample
_flutter.loader.load({
config: {
entryPointBaseUrl: appUrl, // entryPoint (camelCase notation)
},
onEntrypointLoaded: async (engineInitializer) => { // entrypoint (lowercase notation)
const engine = await engineInitializer.initializeEngine({
assetBase: appUrl,
multiViewEnabled: true,
});
window._ourApp = await engine.runApp();
},
