acility);
}
void Playground::removeFacility(int index) {
facilities_.erase(facilities_.begin() + index);
}
double Playground::getFacilityIncomeOnDate(int index, const std::string &date) const {
return facilities_[index].getFlutter 中可以使用 image_picker 插件来实现图片选择器功能,同时可以根据自己的需求对图库样IncomeOnDate(date);
}
double Playground::getTotalIncomeOnDate(const std::string &date) const {
double income = 式进行修改。
下面是一个基于 image_picker 插件的图片选择器示例,其中使用自定义的图库样0;
for (auto facility : facilities_) {
income += facility.getIncomeOnDate(date);
}
return income;
}
式:
```dart
import 'dart:io';
import 'package:flutter/material.dart';
import 'package:image_picker/image_picker.dart';
void maindouble Playground::getTotalIncome() const {
double income = 0;
for (auto facility : facilities_) {
income +=() => runApp(MyApp());
class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
title: facility.getTotalIncome();
}
return income;
}
std::vector<PlayFacility> Playground::getSortedFacilitiesByName() const 'Image Picker Demo',
home: MyHomePage(),
);
}
}
class MyHomePage extends StatefulWidget {
@override
_My {
std::vector<PlayFacility> facilities = facilities_;
std::sort(facilities.begin(), facilities.end(), PlayFacHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
File _image;
Futureility::sortByName);
return facilities;
}
std::vector<PlayFacility> Playground::getSortedFacilitiesByIncome() const getImage() async {
var image = await ImagePicker.pickImage(source: ImageSource.gallery);
setState(() {
_image = image;
{
std::vector<PlayFacility> facilities = facilities_;
std::sort(facilities.begin(), facilities.end(), PlayFac });
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('ility::sortByIncome);
return facilities;
}
void Playground::saveToFile(const std::string &filename) const {
FileIO::Image Picker Demo'),
),
body: Center(
child: _image == null
? Text('No image selected.')
:writeToFile(filename, facilities_);
}
```
主函数(main.cpp):
```c++
#include <iostream>
#include "Playground.h"
int main() {
Playground playground("playground.txt");
int option = 0;
do {
std::cout << " Image.file(_image),
),
floatingActionButton: FloatingActionButton(
onPressed: getImage,
tooltip: 'Pick Image',
child:1. Add a new facility" << std::endl;
std::cout << "2. Remove a facility" << std::endl;
Icon(Icons.add_a_photo),
),
);
}
}
```
在这个示例中,我们使用 ImagePicker.pickImage() std::cout << "3. Get income of a facility on a date" << std::endl;
std::cout << "4 方法来选择图片,通过传递 ImageSource.gallery 参数来打开图库。你可以根据自己的需求来修改图库的样式,比如使用自定义的按钮、图标、字体等。
