screenshot modes

screenshot_modes #
easy screenshot take for your app
screenshot_modes is a flutter package that work as a plugin for device preview package, take automatics screenshots for pages app



setup this plugin #
0- you will need to setup device preview package first before using this plugin. it is just a few step. #
simple mode : #

simple mode you will just select device frame you want and function navigate to page and the plugin will make it work ,
will take screenshot for all your page in all frames in dark and light mode.

setup simple mode : #
1- first define the plugin: #
final simpleScreenShotModesPlugin = SimpleScreenShot(
processor: saveScreenShot,
pages: listPush,
devices: [
Devices.android.samsungGalaxyNote20.identifier,
Devices.ios.iPhone13ProMax.identifier,
Devices.ios.iPadAir4.identifier,
],
lang: [Locale('ar') , Locale('en') ] ,
useToggleDarkMode: true,
);

final listPush = [
ItemScreenMode(function: pushHome, label: 'home'),
ItemScreenMode(function: pushFirst, label: 'first'),
ItemScreenMode(function: pushSecond, label: 'second'),
];
copied to clipboard
2- then pass it to device preview #
runApp(DevicePreview(
builder: (_) => MyApp(),
tools: [
...DevicePreview.defaultTools,
simpleScreenShotModesPlugin
],
));
copied to clipboard
3- also define your push function ( pushHome,pushFirst,pushSecond) define for your page #
Future pushHome(BuildContext context) async {
Navigator.of(navigatorKey.currentContext)
.push(DirectPageRouteBuilder(builder: (_) => HomePage()));
}

Future pushFirst(BuildContext context) async {
Navigator.of(navigatorKey.currentContext)
.push(DirectPageRouteBuilder(builder: (_) => FirstPage()));
}

Future pushSecond(BuildContext context) async {
// we could get data from server;
final data = await ApiService.getData();
Navigator.of(navigatorKey.currentContext).push(DirectPageRouteBuilder(
builder: (_) => SecondPage(
nums: data,
)));
}
copied to clipboard
it could be just Navigator or maybe call some api get data before Navigate like in pushSecond

4- define saveScreenShot function #
this response for saving the image or upload it to some server or that ever you want to do with the image example to save the image in desktop folder
Future<String> saveScreenShot(DeviceScreenshotWithLabel screen) async {
String name = screen.label.join('/');
final path = join(Directory.current.path, 'screenshot', '$name.png');
final imageFile = File(path);
await imageFile.create(recursive: true);
await imageFile.writeAsBytes(screen.deviceScreenshot.bytes);
return '$path saved'; // message printed to device preview plugins windows;
}
copied to clipboard
5- click the new button(screenshot mode) in device preview tabs and that it. #
______
advanced way ( simple way actually depend on it ) #
1- define ScreenShotModesPlugin #
final screenShotModesPlugin = ScreenShotModesPlugin(processor: saveScreenShot, modes: _modes );
copied to clipboard
2- pass screenShotModesPlugin to DevicePreview #
void main() {
runApp(DevicePreview(
builder: (_) => MyApp(),
tools: [
...DevicePreview.defaultTools,
screenShotModesPlugin,
],
));
}
copied to clipboard
3- define saveScreenShot function this response for saving the image or upload it to some server or that ever you want to do with the image example to save the image in desktop #
Future<String> saveScreenShot(DeviceScreenshotWithLabel screen) async {
String name = screen.label.join('/');
final path = join(Directory.current.path, 'screenshot', '$name.png');
final imageFile = File(path);
await imageFile.create(recursive: true);
await imageFile.writeAsBytes(screen.deviceScreenshot.bytes);
return '$path saved'; // message printed to device preview plugins windows;
}
copied to clipboard
4- add item to _modes list #

simple way

final _modes_ = [
ItemScreenMode(function: pushHome, label: 'home'),
ItemScreenMode(function: pushFirst, label: 'first'),
ItemScreenMode(function: pushSecond, label: 'second'),
];
copied to clipboard

with theme mode change


final listPush = [
ItemScreenMode(function: pushHome, label: 'home'),
ItemScreenMode(function: pushFirst, label: 'first'),
ItemScreenMode(function: pushSecond, label: 'second'),
];

final _modes = [
ItemScreenMode(
function: (context) async {
await setModeTo(context, ThemeMode.light);
},
label: "light",
modes: listPush),
ItemScreenMode(
function: (context) async {
await setModeTo(context, ThemeMode.dark);
},
label: "dark",
modes: listPush),
];
copied to clipboard

with theme mode and device frame change

final _mode = [
ItemScreenMode(
function: setDeviceToIphone,
label: "iphone",
modes: listLightDark,
),
ItemScreenMode(
function: setDeviceToNote, label: "note", modes: listLightDark),
];
final listLightDark = [
ItemScreenMode(
function: (context) async {
await setModeTo(context, ThemeMode.light);
},
label: "light",
modes: listPush),
ItemScreenMode(
function: (context) async {
await setModeTo(context, ThemeMode.dark);
},
label: "dark",
modes: listPush),
];
final listPush = [
ItemScreenMode(function: pushHome, label: 'home'),
ItemScreenMode(function: pushFirst, label: 'first'),
ItemScreenMode(function: pushSecond, label: 'second'),
];

Future<void> setDeviceToNote(BuildContext context) async {
DevicePreviewHelper.changeDevice(
context, Devices.android.samsungGalaxyNote20Ultra.identifier);
}

Future<void> setDeviceToIphone(BuildContext context) async {
DevicePreviewHelper.changeDevice(context, Devices.ios.iPhone13.identifier)
}

you could benefid from DevicePreviewHelper class to change device , theme and other helper function
5- click the new button(screenshot mode) in device preview tabs #
_______
what is ItemScreenMode : #
it is represents every screenshot we will take

function parameter is a function that called before take screen
we must navigate to the page you want take screenshot for it
maybe also get some data from database or api before navigate


label parameter is string helps for naming the image inside processor (saveScreenShot)


modes parameter is another list of ItemScreenMode used if we have nested mode
like light/dark for all pages and change frame for all pages
like in above example


could i set function parameter for ItemScreenMode to null ? #
yes when you don't need to do any things before first shot taken maybe when you already inside home page (defalut page) and in right themes mode
tips : don't do that if you have multi nested page

why we must use DirectPageRouteBuilder for navigation #
you must use DirectPageRouteBuilder for navigation like this
Future pushFirst() async {
Navigator.of(navigatorKey.currentContext)
.push(DirectPageRouteBuilder(builder: (_) => FirstPage()));

}

copied to clipboard
because the MaterialPageRoute have 500ms Duration for animations
this will cause as a problem with screenshot
so we must either use DirectPageRouteBuilder or await 500ms Duration after Navigation inside ItemScreenMode function

we prefers to use this plugin on desktop #

TODO : #

resizing the image for every mode ( so we could resized to the size required by google play or app store) ( now could done in saveScreenShot function )
improve the way for naming image .
