Description
Note: This is shamelessly copied from https://stackoverflow.com/questions/59568536/how-to-include-a-webassembly-module-in-a-flutter-web-application because I think this is a bug/is missing documentation.
I'm trying to extend my Flutter Web application with some Rust code via WebAssembly. My project structure looks like this:
lib/
- main.dart
web/
- wasm_demo/
- src/
- lib.rs
- pkg/
- wasm_demo.js
- wasm_demo_bg.wasm
- bootstrap.js
- Cargo.toml
- index.html
The Rust code just creates a String and returns it:
// web/wasm_demo/src/lib.rs
use wasm_bindgen::prelude::*;
#[wasm_bindgen]
pub fn get_string() -> String {
String::from("This is a Rust String!")
}When compiled with wasm-pack build the bytecode ends up in web/wasm_demo/pkg/wasm_demo_bg.wasm. wasm_demo.js is just a JavaScript module exporting the get_string function from wasm_demo_bg.wasm:
import * as wasm from './wasm_demo_bg.wasm';
...
/**
* @returns {string}
*/
export function get_string() {
...
}bootstrap.js imports that module and puts it into the window object:
// bootstrap.js
import * as wasm_demo from "./pkg/wasm_demo";
window.wasm_demo = wasm_demo;index.html loads that bootstrapper prior to launching the actual application:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Rust/WASM/Flutter interop demo</title>
</head>
<body>
<script src="wasm_demo/bootstrap.js" type="module"></script>
<script src="main.dart.js" type="application/javascript"></script>
</body>
</html>And finally, Flutter displays the Rust String:
import 'dart:js';
import 'package:flutter/material.dart';
void main() {
runApp(MyApp());
}
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Rust/WASM/Flutter interop demo',
theme: ThemeData(
primarySwatch: Colors.blue,
),
home: MyHomePage(),
);
}
}
class MyHomePage extends StatelessWidget {
@override
Widget build(BuildContext buildContext) {
var rustString = context["wasm_demo"].callMethod('get_string').toString();
return Scaffold(
appBar: AppBar(
title: Text("Rust/WASM/Flutter interop demo"),
),
body: Center(
child: Text(rustString),
),
);
}
}The problem I have is that wasm_demo_bg.wasm is apparently not included in the bundle:
:44809/wasm_demo/pkg/wasm_demo:1 Failed to load resource: the server responded with a status of 404 (Not Found)Is there any way to tell Flutter that the WebAssembly module is needed in the bundle? Thanks!
