1: I want to use check box but facing this error again and again.. I'm new in flutter what do I do now. https://i.stack.imgur.com/m9PdK.jpg
It seems that to believe the error message that is showing you have mutliple causes:
First the "error getter 'sortFilter' isn't defined means that you either didn't pass the argument or that simply the sortFilter isn't defined in your widget meaning that when you do widget.sortFilter, here sortFilter will be undefined.
Secondly, it appear that for the last error message selectedValue is just not initialized, you certainly put before, the keyword late to that variable and didn't put a value afterward. So try by default giving him true or false and at least you should have this solved.
Anyways, if those solution doesn't not work, please give a better overview or your code especially the widget CarInfoScreen.

When running Mule Debugger, the variable value of the highlighted object shows "United" but the watch at
payload.'1'.typedValue.value[0].airlineName
shows null as in the screenshot below.
How to show the actual value of the watch, "United"?
Thank you
The attribute typedValue of type TypedValue<> is probably an implementation detail that is probably not meant to be used outside the MuleSDK. Try adding a watch for payload.'1'[0] or payload.'1'.value to see if that can be interpreted.
I am having problems when I add an item to a CardList and try to display it using a Carousel. The item is added to the list but when I try to see it through the Carousel the error is shown :
I/flutter (12255): Another exception was thrown: NoSuchMethodError: The method '*' was called on null.
I have tried to not leave anything uninitialized as I have read in similar cases regarding this issue, but it doesn't help.
you can check my code here on my Github profile: https://github.com/varamsky/notes
And this is an image of the emulator screen.

I see your code and find the problem.
In file todoCard.dart in line 93 have this:
child: Text('${(percent*100).toInt()}%'),
This operation in the string (percent*100) not is valid because, for some reason, the percent is null.
You need to verify if percent is null.
PS: In next time, please place the code in answer, to facilitate a response.
PS2: I make a pull request to add a complete gitignore in your repository. This makes the repository easier to clone and work with him :D

I solved this problem while when I added:
textDirection: TextDirection.ltr, below the Row
check ----
If I try to log benchmark->elapsed_time() in post_system hook, it just logs {elapsed_time} as if I called it from a controller.
CodeIgniter documentation says:
"post_system Called after the final rendered page is sent to the browser, at the end of system execution after the finalized data is sent to the browser."
It also says you are supposed to echo the elapsed_time() in a view to show it to the user, but... how is it possible that elapsed_time() is still being calculated after sending the finalized data to the browser?
I feel being lied to.
People keep saying I should use my own marks and get the difference, but that's not the same as using this...
Turns out the documentation also says:
"If the first parameter is empty this function instead returns the {elapsed_time} pseudo-variable. This permits the full system execution time to be shown in a template. The output class will swap the real value for this variable."
I went to the Output class and found the 2 marks it is using: total_execution_time_start and total_execution_time_end and I can use those in the post_system hook.
I have an issue with VSTS manual test cases. When I try to edit one, I got an error message as follows:
An element with the same key already exists in the dictionary

I only have this issue if a test step contains parameters. After refreshing the page and reopening the test case, the color code is black and it doesn't display the Save button. Also, the dropdown of the ... is empty.
Existing tests are fine, running them is also possible. Working with bugs, user stories and tasks is fine.
Screenshots can be found here
Is there a way to workaround this?
This is caused by the parameter name "#length", remove it or rename it to others like "#length1" would works.
This seems to be a bug with VSTS, I have help you created a feedback on MS Connect Page, refer to this link for details: "An element with the same key already exists in the dictionary" error occurs when save a test case contains a parameter named as "length".
I want to verify the text present in placeholder. I have located the element and i am using Assert text command. I've entered the same string in value. On executing it is showing actual value did not match
Use assertAttribute or verifyAttribute command.
Example:
verifyAttribute | css=#search#placeholder | Sample String
Notes:
In the Target column of Selenium IDE, you need to provide the proper path of the element followed by an # sign
and then the name of the attribute. (placeholder in your case)
Using
verifyAttibute will still continue running the test case once an
error is detected while using assertAttribute doesn't.
You need to understand that assertText function can only check static text on your webpage.
You must be getting an error message.
This is perfectly normal.
What can help in this situation is using the assertAttribute or verifyAttribute functions.
Both these functions perform the same task; the former stops the test after receiving an error message in the text box while verifyValue just records the error in the log and runs the next commands.
While giving the target, either specify the XPath or refer by using the name=name#placeholder format.
You can find the name value by inspecting the box with a firefox addon called Firepath which runs with another firefox tool called Firebug. Install them if you don't already have.
Hope this helps!
Xpath contains() is the best way.
driver.find_element_by_xpath('//input[contains(#placeholder,"email")]')
Format : '//tag[contains(#attribute,"value")]'
