You can use Plugin.InputKit from Nuget.

Usage

<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             xmlns:local="clr-namespace:xxx"
             xmlns:input="clr-namespace:Plugin.InputKit.Shared.Controls;assembly=Plugin.InputKit"
             x:Class="xxx.MainPage">


<ContentPage.Content>
 <ListView  x:Name="ProductsListView">
    <ListView.ItemTemplate>
        <DataTemplate>
            <ViewCell>
                <ViewCell.View>
                    <StackLayout Spacing="0">
                        <Label Text="{Binding retail_modified_item_id}" 
                           TextColor="Blue" FontSize="13" />
                        <Label Text="{Binding name, StringFormat='Name : 
                           {0:N}'}" TextColor="black" FontSize="10"  />
                        <Label Text="{Binding retail_price, 
                           StringFormat='Price : {0:N}'}" 
                           TextColor="black" FontSize="10" />
                        <input:CheckBox Text="xxx" Type="Check"/>  
                    </StackLayout>
                </ViewCell.View>
            </ViewCell>                            
        </DataTemplate>
    </ListView.ItemTemplate>
 </ListView>
</ContentPage.Content>        

</ContentPage>

Add/remove value to local collection using OnCheckChanged method. I used this way:

<ListView>
    <ListView.ItemTemplate>
        <DataTemplate>
            <ViewCell>
                <StackLayout Orientation="Horizontal">
                    <Label Text="Some item" />
                    <CheckBox 
                        IsChecked="true" 
                        CheckedChanged="OnCheckedChanged" 
                        HorizontalOptions="EndAndExpand"/>
                </StackLayout>
            </ViewCell>
        </DataTemplate>
    </ListView.ItemTemplate>
</ListView>

If you need to have checkboxes inside a listview, you can use Xamarin.Forms.InputKi (https://github.com/enisn/Xamarin.Forms.InputKit)

Then I would define it like this inside a DataTemplate's ViewCell:

 <input:CheckBox Text="Hello World I'm Option 2" Type="Check"/>

There are also Bindable properties and events which you can use depending on your scenario:

CheckChanged: (Event) Invokes when check changed.

CheckChangedCommand: (Command) Bindable Command, executed when check changed.

Key: (int) A key you can set to define checkboxes as ID.

Text: (string) Text to display description

IsChecked: (bool) Checkbox checked situation. Works TwoWay Binding as default.

Color: (Color) Color of selected check.

TextColor: (Color) Color of description text.

Type: (CheckType) Type of checkbox checked style. (Check,Cross,Star,Box etc.)
