ScreenshotMaker class

A widget for generating images. When you pass a widget as a child and let it work in the simulator, it generates an image.

import 'dart:io';
import 'package:flutter/material.dart';
import 'package:screenshot_maker/screenshot_maker.dart';

void main() {
  runApp(
    ScreenshotMaker(
      // write your absolute path.
      outputFile: File('/Users/your_name/Desktop/simple.png'),
      size: Size(500, 1000),
      child: MaterialApp(
        home: Scaffold(
          appBar: AppBar(),
          body: Text('text'),
        ),
      ),
    ),
  );
}
