解决办法：data:text/html;charset=utf-8;base64,${base64Encode(const Utf8Encoder().convert(_html))}
主要是添加charset=utf-8

  _renderHtml (html)  {
    String _html = '''
          <html>
            <head>
              <meta charset="UTF-8">
            </head>
            <body  onload="SendHight()">
              ${html}
              <script type="text/javascript">window.extents.postMessage(document.body.offsetHeight);</script>
            </body>
        </html>
    ''';
    String _S="data:text/html;charset=utf-8;base64,${base64Encode(const Utf8Encoder().convert(_html))}";
    return _S;
  }

调用方法

            Container(
              height: _htmlHeight,
              child: WebView(
                initialUrl: _renderHtml(widget.item.content),
                javascriptMode: JavascriptMode.unrestricted,
                onWebViewCreated: (WebViewController webViewController) {

                },
                javascriptChannels: <JavascriptChannel>[
                  _SetHtmlHeight(context)
                ].toSet(),
              ),
            )
