【问题描述】：

我在我的 android 项目中包含了颤振模块，颤振模块包含我用来加载应用程序 url 的 webview (flutter_inappwebview)。

我正在打开一个网页视图页面，其中包含用于输入数据的文本字段。当我点击文本字段输入数据时，键盘弹出，屏幕完全变黑。

日志充满以下错误

E/InputMethodManager: b/117267690: Failed to get fallback IMM with expected displayId=134 actual IMM#displayId=0 view=com.pichillilorenzo.flutter_inappwebview.InAppWebView.InAppWebView1df7162 VFEDHVCL. .F...... 0,0-1440,2308

【参考方案1】：

在脚手架中插入：

resizeToAvoidBottomInset: false

【讨论】：

Perfectt.，在创建条形码扫描仪应用程序时为此苦苦挣扎了几天，它只是一行代码哈哈。谢谢老哥！！

我知道设置为 false 会阻止脚手架主体调整大小以适应键盘，这有时可能是不可取的。有没有办法在保持相机开启的同时允许调整大小？或者没有办法解决它..
