flutter webview里加载本地html文件报错？

Question

已经解决了，加上编码就行了

new Uri.dataFromString(snapshot.data, mimeType: 'text/html', encoding: Encoding.getByName('utf-8')).toString(),

想请教一下，webview里加载本地html文件报错是什么情况呢？

加载webview的dart文件

import 'dart:io';
import 'package:flutter/widgets.dart';
import 'package:flutter/material.dart';
import 'package:flutter/services.dart' show rootBundle;
import 'package:flutter_webview_plugin/flutter_webview_plugin.dart';

class WebView extends StatefulWidget {
  WebView({Key key}) : super(key: key);

  @override
  _WebViewState createState() => _WebViewState();
}

class _WebViewState extends State<WebView> {
  Future<String> _getFile() async {
    return await rootBundle.loadString('assets/index.html');
  }

  @override
  Widget build(BuildContext context) {
    return FutureBuilder<String>(
      future: _getFile(),
      builder: (context, snapshot) {
        if (snapshot.hasData) {
          return WebviewScaffold(
            appBar: AppBar(title: Text("Load HTM file in WebView")),
            withJavascript: true,
            appCacheEnabled: true,
            withLocalUrl: true,
            hidden: true,
            allowFileURLs: true,
            url: new Uri.dataFromString(snapshot.data, mimeType: 'text/html').toString(),
          );
        } else if (snapshot.hasError) {
          return Scaffold(
            body: Center(
              child: Text("${snapshot.error}"),
            ),
          );
        }
        return Scaffold(
          body: Center(child: CircularProgressIndicator()),
        );
      },
    );
  }
}

pubspec.yaml

flutter:
  uses-material-design: true

  assets:
    - assets/index.html
