Good morning! I have a problem with the web flutter, when I run the application on a mobile it works well, but when it comes to the web it does not work, the problem is on the server side when I call a feature at the server level. Here is the land:
MissingPlugingException(No implementation found for method check on channel plugins.
flutter.io/connectivity)
connectivity plugin does not support web, use connectivity_plus instead.

I need to clarify a doubt in the development of Dapp, when creating a mobile app with flutter can I use web3 to connect with the wallet and the blockchain?
[Edit 2021-12-02] I just found this https://pub.dev/packages/flutter_web3, it is web only but seems to be compatible with WalletConnect QR codes connection, so it is probably worth a try.
Original answer:
I believe you can check out flutter_web3_provider but it only works for web.
I believe you can also use WalletConnect to support mobile wallets like these ones, but I haven't found a wrapper/implementation for flutter so you would need to implement that. But the good news is you would be able to use it in native apps. I see there is a react-native implementation so hopefully somebody will write the flutter implementation soon. You can support/like the request here.
Also you can directly sign and send transactions to an RPC server (a more direct gate to the blockchain) using web3dart, but of course you would need to ask for and/or store the user's private key, which is probably not what you want.
I have a flutter app, works well on mobile, am trying to have the same app on web. am using moor to sync and store data locally incase there is no internet and when internet is back it syncs with the server. Now when I try to run the same app on the web, moor is complaining
Error: MissingPluginException(No implementation found for method getDatabasesPath on channel com.tekartik.sqflite)
the plugin says it supports web, from here. Am not finding much information on how to resolve this, how can I configure moor to run on the web without that error?
The plugin moor you are using is built on top of sqlite, which itself is not supported on web, and at bottom of moor plugin page also it's mentioned that web support is experimental now.
Sqlite plugin doesn't has support for web yet, but it does support android, ios and Macos. I would suggest anyone facing this problem to use other databases or cloud based databases instead of sqlite if you are using flutter web. Hope the plugin gets supported on web also.
Update:
You can try this example to use sqlite on web, it might work.
Got the same error when first run the web app.
If you follow clean architecture you can easily provide the right "database" instance.
This is what I did:
Create a local data store interface
Check if web using kIsWeb
If kIsWeb it true I return an in memory cache otherwise I just return the mobile app database that you already implemented for you Android and iOS apps
I’m using Ionic with Angular to write an iOS and Android app.
But most of the development I use ionic serve with Chrome, it’s fast and simple.
But now I realized that it’s getting harder when I have to use the native HTTP API to do fundamental things like talking to a rest api on my server. The native HTTP api is working for the iOS/Android app in production, but not in the web app mode I’m using for development.
I know that I there are options like live reload for iOS and Android but they are still lazy in my point of view.
So I’m asking you:
Do you prefer developing directly with iOS/Android emulator/devices or are you also using the web app and found a way around the troubles above?
there is no way you can test native HTTP on the browser. you have to use an emulator or a native device. BUT, for testing UI you can run the command ionic serve --lab instead of ionic serve. do it and see the difference.
to test HTTP on the browser you must use HttpClient.
Recently, I have been exploring the Flutter API tools and builds, even the flutter-web project. So what I really want to understand is the flutter-web support which makes it possible to compile an existing or new app into a web app, to run on web browsers. The question is: "What are the possible side effects you are likely going to experience when using flutter-web to build web apps". Thanks in advance.
The main reason why it is not advised to use flutter-web is beacuse it is not yet in a stable version.
Therefore if offers low-performance compare to normal web-apps.
For more details on the advantages and disadvantages of using flutter-web.
Check the article below. It will be of help.

I hope this answers your question.
I am using firebase plugin to authentication with email and password in flutter web. I am done with this one.
Now I want to authenticate flutter web with phone_auth. I am using the same plugin and in this plugin, a future method which is called signInWithPhoneNumber(String phoneNumer, ApplicationVarifier verifier). I follow the rule on the firebase for application verifier. There, I learn about ReCaptchaVarifier which verifies the user with reCaptcha technique. But there is no way to integrate reCaptcha in flutter web.
If you solved my problem then it will be great opportunity for me to getting my job. Thanks I am waiting for your response
Flutter for Web is currently in development, therefore firebase support isn't yet ready... It may come in the near future. Good luck with your project!
As at now Flutter Web is not yet ready for Production and it does not support these yet.
You should consider using other dart frameworks.
And No, you can not write HTML code for flutter web.
