We have created a theme editor
where you can define your own theme. We have also defined some themes ourselves, which can be installed and used directly. Below is a usage example:
import CodeMirror from '@uiw/react-codemirror';
import { javascript } from '@codemirror/lang-javascript';
import { okaidia } from '@uiw/codemirror-theme-okaidia';
const extensions = [javascript({ jsx: true })];
export default function App() {
return (
<CodeMirror
value="console.log('hello world!');"
height="200px"
theme={okaidia}
extensions={[javascript({ jsx: true })]}
/>
);
}
import CodeMirror from '@uiw/react-codemirror';
import { createTheme } from '@uiw/codemirror-themes';
import { javascript } from '@codemirror/lang-javascript';
import { tags as t } from '@lezer/highlight';
const myTheme = createTheme({
theme: 'light',
settings: {
background: '#ffffff',
foreground: '#75baff',
caret: '#5d00ff',
selection: '#036dd626',
selectionMatch: '#036dd626',
lineHighlight: '#8a91991a',
gutterBackground: '#fff',
gutterForeground: '#8a919966',
},
styles: [
{ tag: t.comment, color: '#787b8099' },
{ tag: t.variableName, color: '#0080ff' },
{ tag: [t.string, t.special(t.brace)], color: '#5c6166' },
{ tag: t.number, color: '#5c6166' },
{ tag: t.bool, color: '#5c6166' },
{ tag: t.null, color: '#5c6166' },
{ tag: t.keyword, color: '#5c6166' },
{ tag: t.operator, color: '#5c6166' },
{ tag: t.className, color: '#5c6166' },
{ tag: t.definition(t.typeName), color: '#5c6166' },
{ tag: t.typeName, color: '#5c6166' },
{ tag: t.angleBracket, color: '#5c6166' },
{ tag: t.tagName, color: '#5c6166' },
{ tag: t.attributeName, color: '#5c6166' },
],
});
const extensions = [javascript({ jsx: true })];
export default function App() {
const onChange = React.useCallback((value, viewUpdate) => {
console.log('value:', value);
}, []);
return (
<CodeMirror
value="console.log('hello world!');"
height="200px"
theme={myTheme}
extensions={extensions}
onChange={onChange}
/>
);
}
initialState
to restore state from JSON-serialized representationCodeMirror allows to serialize editor state to JSON representation with toJSON function for persistency or other needs. This JSON representation can be later used to recreate ReactCodeMirror component with the same internal state.
For example, this is how undo history can be saved in the local storage, so that it remains after the page reloads
import CodeMirror from '@uiw/react-codemirror';
import { historyField } from '@codemirror/commands';
// When custom fields should be serialized, you can pass them in as an object mapping property names to fields.
// See [toJSON](https://codemirror.net/docs/ref/#state.EditorState.toJSON) documentation for more details
const stateFields = { history: historyField };
export function EditorWithInitialState() {
const serializedState = localStorage.getItem('myEditorState');
const value = localStorage.getItem('myValue') || '';
return (
<CodeMirror
value={value}
initialState={
serializedState
? {
json: JSON.parse(serializedState || ''),
fields: stateFields,
}
: undefined
}
onChange={(value, viewUpdate) => {
localStorage.setItem('myValue', value);
const state = viewUpdate.state.toJSON(stateFields);
localStorage.setItem('myEditorState', JSON.stringify(state));
}}
/>
);

Flutter Google cross-platform UI framework has released a new version 1.20 stable.
Flutter is Google’s UI framework to make apps for Android, iOS, Web, Windows, Mac, Linux, and Fuchsia OS. Since the last 2 years, the flutter Framework has already achieved popularity among mobile developers to develop Android and iOS apps. In the last few releases, Flutter also added the support of making web applications and desktop applications.
Last month they introduced the support of the Linux desktop app that can be distributed through Canonical Snap Store(Snapcraft), this enables the developers to publish there Linux desktop app for their users and publish on Snap Store. If you want to learn how to Publish Flutter Desktop app in Snap Store that here is the tutorial.
Flutter 1.20 Framework is built on Google’s made Dart programming language that is a cross-platform language providing native performance, new UI widgets, and other more features for the developer usage.
Here are the few key points of this release:
In this release, they have got multiple performance improvements in the Dart language itself. A new improvement is to reduce the app size in the release versions of the app. Another performance improvement is to reduce junk in the display of app animation by using the warm-up phase.
If your app is junk information during the first run then the Skia Shading Language shader provides for pre-compilation as part of your app’s build. This can speed it up by more than 2x.
Added a better support of mouse cursors for web and desktop flutter app,. Now many widgets will show cursor on top of them or you can specify the type of supported cursor you want.
Autofill was already supported in native applications now its been added to the Flutter SDK. Now prefilled information stored by your OS can be used for autofill in the application. This feature will be available soon on the flutter web.
A new widget for interaction
InteractiveViewer
is a new widget design for common interactions in your app like pan, zoom drag and drop for resizing the widget. Informations on this you can check more on this API documentation where you can try this widget on the DartPad. In this release, drag-drop has more features added like you can know precisely where the drop happened and get the position.
In this new release, there are many pre-existing widgets that were updated to match the latest material guidelines, these updates include better interaction with Slider
and RangeSlider
, DatePicker
with support for date range and time picker with the new style.
pubspec.yaml
formatOther than these widget updates there is some update within the project also like in pubspec.yaml
file format. If you are a flutter plugin publisher then your old pubspec.yaml
is no longer supported to publish a plugin as the older format does not specify for which platform plugin you are making. All existing plugin will continue to work with flutter apps but you should make a plugin update as soon as possible.
Visual Studio code flutter extension got an update in this release. You get a preview of new features where you can analyze that Dev tools in your coding workspace. Enable this feature in your vs code by _dart.previewEmbeddedDevTools_
setting. Dart DevTools menu you can choose your favorite page embed on your code workspace.
The updated the Dev tools comes with the network page that enables network profiling. You can track the timings and other information like status and content type of your** network calls** within your app. You can also monitor gRPC traffic.
Pigeon is a command-line tool that will generate types of safe platform channels without adding additional dependencies. With this instead of manually matching method strings on platform channel and serializing arguments, you can invoke native class and pass nonprimitive data objects by directly calling the Dart
method.
There is still a long list of updates in the new version of Flutter 1.2 that we cannot cover in this blog. You can get more details you can visit the official site to know more. Also, you can subscribe to the Navoki newsletter to get updates on these features and upcoming new updates and lessons. In upcoming new versions, we might see more new features and improvements.

Flutter is an open-source UI toolkit for mobile developers, so they can use it to build native-looking** Android and iOS** applications from the same code base for both platforms. Flutter is also working to make Flutter apps for Web, PWA (progressive Web-App) and Desktop platform (Windows,macOS,Linux).
Flutter was officially released in December 2018. Since then, it has gone a much stronger flutter community.
There has been much increase in flutter developers, flutter packages, youtube tutorials, blogs, flutter examples apps, official and private events, and more. Flutter is now on top software repos based and trending on GitHub.
What is Flutter? this question comes to many new developer’s mind.
Flutter means flying wings quickly, and lightly but obviously, this doesn’t apply in our SDK.
So Flutter was one of the companies that were acquired by **Google **for around $40 million. That company was based on providing gesture detection and recognition from a standard webcam. But later when the Flutter was going to release in alpha version for developer it’s name was Sky, but since Google already owned Flutter name, so they rename it to Flutter.
Flutter is used in many startup companies nowadays, and even some MNCs are also adopting Flutter as a mobile development framework. Many top famous companies are using their apps in Flutter. Some of them here are
and many more other apps. Mobile development companies also adopted Flutter as a service for their clients. Even I was one of them who developed flutter apps as a freelancer and later as an IT company for mobile apps.
