I am trying to use Flutter blue_thermal_printer to print a receipt. The example code, unchanged, prints the images fine but no text.
Is this an issue with a very cheap printer? The printer is set to English.
The example code is here.

I am making a Flutter app, and I am using webview here.
It all goes fine but when it comes to image, it just fails.
Other text contents are all fine.
I tried several things but all failed.
You can replicate the test by this url
It appears fine from the browser but images never appaer only in flutter webview
This is my flutter code for the webview
I found the answer by myself. It was because the image source was referred as "http:". I just put the following tag and it solved like a charm
In my application I need to show options for Show more and Show less for the attributed text. If there is the simple Text then I could manage the things by using .subString function for first few characters and full text.
But here in my case I am using flutter_html lib. Here if I take data using .subString then attributed text getting disturbed which creates wrong output.
For consideration my text is as mentioned below:
The system requirements are\r\n :\r\n An internet connection – broadband wired or wireless (3G or 4G/LTE)\r\n Speakers and a microphone (required in case of interactive sessions) – Built-in, USB plug-in, or wireless Bluetooth\r\n A webcam or HD webcam - built-in, USB plug-in (required in case of interactive sessions)\r\n CLICK HERE to view the System Requirements for Zoom.\r\n
Consider the image as mentioned below:
Is there something else can be done here to achieve this feature without using .subString feature!!??

We're currently developing a game in Unity (2019.4.28f1). This game is played internationally. We'd like to add support for languages other than common Latin written languages. Currently, we're trying to implement support for Burmese, but aren't making much progress.
Finding fonts to display Burmese isn't a big issue. As you can see in the image below, we manage to display all characters that are supposed to be displayed.
However, the big problem here is that the displayed order of symbols isn't the same as what it's supposed to be (see image below for the desired result).
We've tried several fonts that use either Unicode or Zwagyi encoding, but none of them seem to display characters in the correct order. Currently, we're using a padauk font from here, which is supposedly Unicode encoded. Then, within Unity, we applied to following settings to that font:
So, if one of you knows more about this and can share some information with me, that would be much appreciated!
Thanks.
We've already found a solution for this! Before setting the text of the text component convert the Unicode codes to Zwagyi and it'll display the text in the correct order!
All the credits go to this guy who put in the effort to make a tool for these use cases!
Of course, you still need a (Unicode) font that supports these (Burmese) symbols.
Example:
Text textComponent = GetComponent<Text>();
textComponent.text = mmfont.Net.Converter.Uni2ZG(yourUnicodeText);
I'm now building a listview to display fonts from the UIFonts framework. However, for using UIPasteboard.general.string, the fonts are not copied to the clipboard and only the plain text is transferred.
I've tried including the MobileCoreServices framework and use kUTTypeRTF to implement it. But there is no detailed documentation on it.
May I know how can I build a custom font list and allowing the text be selected and pasted with its font styling onto the other applications (like Notes or Facebook post), just like the font generator hosted online?
I'm now working on the two following UIFonts, but I'm not able to keep its formatting while pasting from the clipboard.
let fonts: [String] = ["BodoniSvtyTwoOSITCTT-Book", "ChalkboardSE-Regular"]
You cannot copy-paste text with a font on your iPhone.
FancyLetters also cannot do this. It just shows you characters that look like they are printed.
For example, the letter "A" has variations: "𝓐", "𝒜", "𝔸". But this is not font-altered text, StackOverflow does not allow it either. These are characters from Unicode table. They are the same characters as "A" or "B", except that without special modifiers the keyboard will not print them for you, e.g. SHIFTOPTIONK = .
Any font is superimposed over Unicode characters.
I recommend you to read an excellent article Emoji under the hood. It's about how emoji are drawn on devices, but it also explains a lot about the construction of characters and how they are rendered on different devices.
Or font generator also cannot do this. It just shows you characters that look like they are printed
I have an app that retrieves a user's stream and puts it into a UITableView. However, some include emojis (those little smile faces in iOS), and they just return as boxes in my UILabel.
I've done some research, and I still can't figure it out. Does the text type need to be changed?
Thanks!
Please explain your problem better,from the piece that i understood,notice that emojis have native support in iPhone,so any app can display an emoji in a text box,i recommend you to check the methods you're using to add text to the uitableview and the text encoding from the string which is being displayed,also you could check this link
use NSString drawinrect to display emoji instead of drawGlyphsForGlyphRange.
