Problem related to back-end and have nothing to do with Flutter.

Basic Authentication works a little differently with the requests library. You can do something like this instead:

I'm curious. Why did you think none or all would match only messages with attachments?

As @triplee says, there's no real definition of attachment so you'll have to fix a definition yourself. But you could approximate, and e.g. move all multipart messages, or all messages with image parts, all messages with PDF parts or all messages for which a bodypart has been explicitly labelled as an attachment (which happens now and then). The search keys are, respectively, header content-type multipart, header content-type image/, header content-type application/pdf and header content-disposition attachment.

The first of these four examples will work well, the other three will work with some servers but far from all, because the specification says "…has a header with…", which one may take to mean "among the message headers" or "among either the message headers or the per-part headers". Good luck with your server.

You can also use or to join several of the conditions.

Modify delete() by adding row object as parameter in template like below to get the corresponding delete object

sendRedirect is sending a response code like 302 or 304 (I assume 302 Temporary Redirect) to the browser and a Location header telling the client where to go instead. This is then handled transparently by the browser, without it ever having to display anything.

To see the HTTP response for yourself use curl -v http://yourendpoint, or use Postman if you prefer a browser based tool. Or you can look at the request/response in your browser dev tools, under the network tab (you might have to find an option that doesn't clear the inpector history on page load).

Alternatively you would pass the redirect url to the page and do the redirect later with javascript.

You could respond with something like this, to display the page and redirect after 3 seconds:

Because the initial value of state details is empty {}. details only update when you call api success. Before that, details kept the value {}

You can check like this:

The url path should include an id parameter:

First of all, Axios GET method does not have any request body. But you are trying to use it in the MongoDB query. - "TotalBalanceModelTemplate.find(request.body.totalBalance, (error, data) => {".

The find query should be object {}. If require pass on conditions to it.

First point, to print only "totalBalance" output. Use, console.log(resp.totalBalance);

Second point, to handle records length, have a if else condition,

Try this:
