我已经创建了一个带有底部表和列表视图构建器的应用程序。在底部，当我将其向上拖动时必须出现一个文本按钮底部表必须出现。底页上有一个表格。我用 SingleChildScrollView 包裹了底页。但是当我单击 TextFormField 键盘时，我可以滚动底部工作表。但是我无法将其向下拖动并关闭底部工作表。即使我按下手机中的后退箭头以摆脱键盘。

import 'package:flutter/material.dart';

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

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

class _HomeState extends State<Home> {

  @override
  Widget build(BuildContext context) {
    var width = MediaQuery.of(context).size.width;
    return Scaffold(

        resizeToAvoidBottomInset: false,
        body: Stack(
                children: [
                  ListView.builder(
                      itemCount: 1,
                      itemBuilder: (context, index) {
                        return Card(
                          );
                      }),
                  Positioned(
                    bottom: 0,
                    child: GestureDetector(
                      onPanEnd: (details) {
                        if (details.velocity.pixelsPerSecond.dy < 10) {

                          //Bottom Sheet.................................................................................................................

                          showModalBottomSheet(
                              shape: RoundedRectangleBorder(
                                borderRadius: BorderRadius.vertical(
                                    top: Radius.circular(25)),
                              ), …

我有一个自定义的BottomSheetDialog布局，我创建了可绘制的布局，它具有顶角圆角矩形。BottomSheetDialog布局背景是 a Linearlayout，我将可绘制对象应用于布局。底部工作表的顶角正确舍入，但线性布局的另一个布局底部不是圆角的（方形和白色见下图），并且它不在布局中.xml 文件。它就像正方形顶部的圆角矩形。我无法摆脱那个正方形。

以下是我的定制底板样本

public abstract class EmployeeBottomSheetDialog extends BottomSheetDialog {

    private Context context;
    private Activity activity;
    private RecyclerView employeeRecyclerView;
    private EditText searchEditText;
    private DataBase dataBase;
    private ArrayList<Employe> employeeList = new ArrayList<>();
    private ArrayList<Employe> employeeSelectedList = new ArrayList<>();
    private SelectEmployeeAdapter selectEmployeeAdapter;
    private ImageButton closeSearchImageButton;

    public EmployeeBottomSheetDialog(@NonNull Context context, List<Employe> selectedEmployeeList) {
        super(context,R.style.BottomSheetDialogStyle);
        this.context = context;
        this.activity = (Activity) context;
        if(!selectedEmployeeList.isEmpty()){
            employeeSelectedList.clear();
            employeeSelectedList.addAll(selectedEmployeeList);
        }
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.employee_bottom_sheet_dialog);
    }
} …
