  根据错误提示修改代码，重选提交。

• flutter-format 格式化

  Format Flutter Code......................................................Failed
  - hook id: flutter-format
  - files were modified by this hook

  钩子会格式化代码，stage 格式化后的代码，重新提交。

• flutter-import-sorter import 头文件排序

  // Dart imports:
  import 'dart:developer';
          
  // Flutter imports:
  import 'package:flutter/material.dart';
          
  // Project imports:
  import 'package:pre_commit_demo/widget.dart';
