有没有一种方法可以在浮动代码上实现此对话框?

如何解决有没有一种方法可以在浮动代码上实现此对话框?

几天以来,我一直试图在飞镖语言上复制此代码和布局(我的大脑快要筋疲力尽),以便与IOS设备一起使用(当然没有可用性结果)。这就是我要寻找的:

View

我尝试过使用带有列的窗口小部件的行,由我自己用原始代码实现,等等。 这是Android Studio中使用的代码:

MainActivity.java

import androidx.appcompat.app.AppCompatActivity;

import android.app.AlertDialog;
import android.os.Bundle;
import android.view.View;
import android.widget.CheckBox;
import android.widget.LinearLayout;
import android.widget.Switch;

import java.util.ArrayList;

public class MainActivity extends AppCompatActivity {

    private AlertDialog dialog;

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

        ArrayList<String> catNames = new ArrayList<>();
        
        for (int i = 0; i < 15; i++)
            catNames.add("Category " + i);

        findViewById(R.id.button).setOnClickListener(v -> {

            AlertDialog.Builder dialog = new AlertDialog.Builder(this);
            final View view = View.inflate(this,R.layout.dialog,null);

            LinearLayout leftSide = view.findViewById(R.id.leftCat);
            LinearLayout rightSide = view.findViewById(R.id.rightCat);

            Switch all = view.findViewById(R.id.all);
            all.setVisibility(View.VISIBLE);

            if (catNames.size() % 2 == 0) {
                for (int i = 0; i < catNames.size() / 2; i++) {
                    CheckBox categoryCheckBox = new CheckBox(this);
                    categoryCheckBox.setText(catNames.get(i));
                    categoryCheckBox.setTag("checkBox" + i);
                    leftSide.addView(categoryCheckBox);
                }

                for (int i = catNames.size() / 2; i < catNames.size(); i++) {
                    CheckBox categoryCheckBox = new CheckBox(this);
                    categoryCheckBox.setText(catNames.get(i));
                    categoryCheckBox.setTag("checkBox" + i);
                    rightSide.addView(categoryCheckBox);
                }
            } else {
                for (int i = 0; i < catNames.size() / 2 + 1; i++) {
                    CheckBox categoryCheckBox = new CheckBox(this);
                    categoryCheckBox.setText(catNames.get(i));
                    categoryCheckBox.setTag("checkBox" + i);
                    leftSide.addView(categoryCheckBox);
                }

                for (int i = catNames.size() / 2 + 1; i < catNames.size(); i++) {
                    CheckBox categoryCheckBox = new CheckBox(this);
                    categoryCheckBox.setText(catNames.get(i));
                    categoryCheckBox.setTag("checkBox" + i);
                    rightSide.addView(categoryCheckBox);
                }
            }

            dialog.setView(view);

            this.dialog = dialog.create();
            this.dialog.show();

            view.findViewById(R.id.select).setOnClickListener(v1 -> {
                String nameCategories = "";

                for (int i = 0; i <catNames.size(); i++) {
                    CheckBox categoryChecker = view.findViewWithTag("checkBox" + i);
                    if (categoryChecker.isChecked())
                        nameCategories = nameCategories.concat((i + 1) + ",");
                }

                System.out.println("Selected categories are: " + nameCategories);

                    this.dialog.dismiss();
            });

            view.findViewById(R.id.delete).setOnClickListener(v1 -> this.dialog.dismiss());

            view.findViewById(R.id.cancel).setOnClickListener(v1 -> this.dialog.dismiss());
        });

    }
}

无论如何,这是我当前的Dart代码(假设变量 类别 与上述相同):

Future<String> _showMyDialog() async {
    return showDialog<String>(
      context: context,barrierDismissible: true,// user must tap button!
      builder: (BuildContext context) {
        return AlertDialog(
          content: Column(
            children: [
              Row(
                children: [
                  getTextWidgets(categories),getTextWidgets2(categories),],),Container(),Row(
                children: [
                  Expanded(
                    child: Container(),Expanded(
                    child: Container(),);
      },);
  }

  Widget getTextWidgets(List<String> strings) {
    List<Widget> list = new List<Widget>();
    for (var i = 0; i < strings.length / 2; i++) {
      list.add(Row(
        mainAxisSize: MainAxisSize.min,children: [
          Checkbox(
            key: Key(i.toString()),value: false,onChanged: (value) {},Text(strings[i],style: TextStyle(fontSize: 10.0,textAlign: TextAlign.justify,)
        ],));
    }
    return new Column(children: list,crossAxisAlignment: CrossAxisAlignment.start,);
  }

  Widget getTextWidgets2(List<String> strings) {
    List<Widget> list = new List<Widget>();
    for (var i = 0; i < strings.length; i++) {
      list.add(Row(
        children: [
          Checkbox(
            key: Key(i.toString()),Text(strings[i]),));
    }
    return new Column(children: list);
  }

结果如下:
