Flutter 如何创建这样的按钮

我想在Flutter 中创造这样的纽扣. 好的，我知道Text1和Text2必须在Row()中. 我不知道要创建这个对齐，文本1必须居中，文本2必须右对齐.

我的代码

import 'package:flutter/material.dart';
import 'package:streeti/static/static_colors.dart';

class ButtonWithBlue extends StatelessWidget {
  const ButtonWithBlue({Key? key, required this.text1, required this.text2})
      : super(key: key);

  final String text1;
  final String text2;

  @override
  Widget build(BuildContext context) {
    return Padding(
      padding: const EdgeInsets.all(8.0),
      child: ClipRRect(
        borderRadius: const BorderRadius.all(Radius.circular(20)),
        child: Container(
          height: 75,
          width: double.infinity,
          decoration: BoxDecoration(
            color: Colors.white12,
            border: Border.all(
              color: AppColors.BlueColor,
              width: 1.0,
            ),
          ),
          child: RawMaterialButton(
            onPressed: () {},
            splashColor: Colors.blue,
            child: Stack(
              children: [
                Positioned(
                  right: -20,
                  top: -25,
                  height: 120,
                  width: 120,
                  child: Container(
                    decoration: ShapeDecoration(
                      color: AppColors.BlueColor,
                      shape: const CircleBorder(),
                    ),
                  ),
                ),
                Container(
                  alignment: Alignment.center,
                  child: Row(
                    mainAxisAlignment: MainAxisAlignment.spaceBetween,
                    children: [
                      Text(
                        text1,
                        style: TextStyle(color: Colors.black, fontSize: 18),
                      ),
                      SizedBox(
                          width: 8), // Add some space between text1 and text2
                      Text(
                        text2,
                        style: TextStyle(color: Colors.black, fontSize: 18),
                      ),
                    ],
                  ),
                ),
              ],
            ),
          ),
        ),
      ),
    );
  }
}

如何构建这个按钮，使文本1在中间，文本2在右侧？(如图所示) 正如我所写的，我知道我应该使用Row()，但在本例中我不知道如何使用它. SpaceBettwen+中心？
