feat: change serving static file directory

[utamori]

Description

I would like to distribute Flutter Web apps on Frog. The directory structure should look like this Flutter does not allow you to specify the output path at build time. by moving frontend/build/web to public folder apps can be serve on Frog If we could specify a path other than public in Frog to serve static files, this one step would be eliminated.

├── frontend  // Flutter Web Project
│  ├── build
│    └── web
├── public
├── pubspec.yaml // Frog Server
├── routes

Requirements

• [ ] Can specify any one path other than public. For example, frontend/build/web.

Additional Context

There is a package that does the same thing with go server

It would be very useful for certain applications if Frog and Flutter Web could do the same thing!

https://github.com/shibukawa/frontend-go

//go:build release

package webapp

// ↓this folder is decided by your frontend framework

//go:embed frontend/build/*
var asset embed.FS

init() {
    frontend.SetFrontAsset(asset, frontend.Opt{
        FrameworkType: frontend.NextJS, // select: NextJS, VueJS, SvelteKit, SolidJS
    })
}

Hi @utamori 👋 Thanks for opening an issue!

This can be achieved using a custom entrypoint.

import 'dart:io';

import 'package:dart_frog/dart_frog.dart';

Future<HttpServer> run(Handler handler, InternetAddress ip, int port) {
  final cascade = Cascade()
      .add(createStaticFileHandler(path: 'frontend/build/web'))
      .add(handler);
  return serve(cascade.handler, ip, port);
}

Let me know if that helps 👍

Closing for now since there aren't any actionable next steps. Feel free to comment with any additional questions and I'm happy to continue the conversation 👍

@felangel thanks! It worked fine. It would be helpful if the documentation mentioned how to do this https://dartfrog.vgv.dev/docs/basics/serving-static-files
