How to translate the text in the flutter app into sign language? - flutter

I want to make an app that can change its language to sign language but I couldnt find any resources or packages that can help me change text to sign language

What do You mean when You write about "sign language"?
You can use this package: https://pub.dev/packages/localization and detect system language or manually choose language. How to set manually language? For example You can create dropdown with list of supported languages and switch langue every time, when You change app language on dropdown button.

By the plugins I writtend you have documentations but you also can go to youtube and look a tutorial about them.
Next time you can simple google what you want to have or go to pub.dev and writte in the search bar what you want.

How to get Language Code from a String in Flutter | Flutter

I'am creating a social media platform. So there is a comment section. I created a translating function to translate any language comment to english (like in instagram or youtube). But the problem is if the language in the comment is already in english i don't want to show the 'Translate' button below to that comment. So how can i detect the language or language code from that comment to make this functionality. Is there any package available to detect the language code from the string.
Eg: If the comment is 'Hello how are you'. Then i dont want to show that translate button under this comment. But if the comment is 'नमस्ते कैसी हो तुम. I want to show translate button. I want to detect wheather the language is in english 'en' or not.
I had this problem too and following link helped me to get these things successfully-

How to change the language of the Google Places Autocomplete results?

Is it possible to change the result language of the Google Places Autocomplete iOS component (similar to changing it when using JavaScript but in Swift)? Specifically I would like to change the search results language.
Per default it seems to be set to the phone's system language meaning that on my German phone I get German city names and on my English phone I get English ones.
[EDIT]: I'm using the Google Placepicker Library that can be installed via Cocoa Pods. My code looks very similar to the first code snippet on the linked page.

Speech to text in multiple languages

i have success fully implemented the ispeech API see http://www.ispeech.org/developers for my app to convert speech to text(see the demo app in the sdk http://www.ispeech.org/instructions/sampleprojects/iphone/IntegrationGuide.html). But unfortunately it takes what we speak as only in english and translte it to text.
what i need.
There is a "speak" button that listens what the user spokes and convert it to text(that works fine for english). Also another button that allows the user to select a language as seen in this appscreenshot( http://screencast.com/t/7vBFH565qD). So when the user speaks in the selected language it should get converted to the same language. In my case whatever we speak it takes the input only in english..
Thanks all..
iSpeech also supports more languages, you can find the list with their corresponding locale identifiers here:
http://www.ispeech.org/api
To set a new language you have the "ISpeechSetLocale" method
[_iSpeech ISpeechSetLocale:#"fr-FR"];
http://www.ispeech.org/developer/iframe?src=/iphonesdkdoc/
Why cant you use the NUANCE API which supports speech to text in multiple languages. see the following link and register there to use their iOS sdk .

How to set the language of iPhone at the run time

I have Login view on which I want to provide drop-down for language selection. So is it possible to change the language of application at the run-time.
You need to set up your own Translation-Framework. So read out the selected language and present the actual language for the user.
Apple, won't give you something in this direction. It's only possible to use NSLocalizedString(#"Key", #"Description")
No ! What I do is using my own translation framework to support just that !
