pharse | Fastest PHP HTML Parser | Parser library

I cant able to retrive the data from Firestore and getting Error as below,

════════ Exception caught by widgets library ═══════════════════════════════════════════════════════ The following assertion was thrown building StreamBuilder(dirty, state: _StreamBuilderBaseState#e568b): A build function returned null.

The offending widget is: StreamBuilder Build functions must never return null.

To return an empty space that causes the building widget to fill available room, return "Container()". To return an empty space that takes as little room as possible, return "Container(width: 0.0, height: 0.0)".

The relevant error-causing widget was: StreamBuilder file:...dart:140:15 When the exception was thrown, this was the stack:

#0 debugWidgetBuilderValue. (package:flutter/src/widgets/debug.dart:300:7) #1 _Closure.call (dart:core-patch/function.dart) #2 debugWidgetBuilderValue (package:flutter/src/widgets/debug.dart:321:4) #3 ComponentElement.performRebuild (package:flutter/src/widgets/framework.dart:4569:7) #4 StatefulElement.performRebuild (package:flutter/src/widgets/framework.dart:4737:11) ...

Below is my code.

My goal is to search within multi diamensional array using Preg Match (just LIKE Operator Search in my SQL), I tried all the possible ways which I know but nothing works for me. My current search code works well but only with the exact match, I want to do it search titles and categories only from the array so that it will matches with the pharse %Action% and extract the possible value or array

Here is my PHP code

i have .cert file. .key file and Password pharse and end point. We are using keyStore, we are using file system. How can i pass these in my karate request.

i have some problem, i learn using request and json but i have this problem

r2 = requests.get('https://poloniex.com/public?command=returnTicker') usdt_btc_ask = r2.json(['USDT_BTC']['lowestAsk'])

and error

TypeError: list indices must be integers or slices, not str

this code is working without error

This answer uses assertion( Rest == [] )?

I have the following query

I need to créate a PDF file in memory within a web api and send it I do créate the PDF and the web api send it, but I can't open it onece recived.

I do créate the PDF as a byte array with this:

I want to get all the request and response details, and I'm considering save them to ngx.log.

I use such code to save them, I want to get a length of 5000 chars from the response body, but in the error.log file, it only saved a part of the response data for each response, which is much shorter than 5000.

I've learned linux and there's my homework:

1. Show all files and directories in /usr and save the result in file usr.txt:

2. Show all files in /usr/bin and stop when the screen is full:
   Hint: use command pipe and more

3. Find all files in /etc that the file name contains the word “log”:
   Hint: use command grep

1.I searched copy command on google but there's just some commands about copy file not contents and I also use Y1G command but there're nothing happen.

2.I absolutely don't have any idea about how to pharse "the screen is full" by commands

3.I've use command find path -log /etc but there're no right result
