QUESTION
I have a report generated by three parameters. An user and 2 range date fields.
When all fields are filled, the report can be generated by Gerar button.

Answered 2021-May-14 at 08:15This is a good rule of thumb:
- If you know the exactly one place you want to notify, use a direct call.
- If you don't know how many, or which, places you want to notify, emit a signal.
QUESTION
I am using 'Syncfusion PDF viewer' to open PDF files in android. I am using 'Dio' and 'Path_provider' to download and save a file on its first time open so that it can be opened from the local storage without internet. The problem I am facing, when I am trying to open a PDF file from local storage (after it is already downloaded and saved), facing performance lag there in the page transition. I am sharing here the full code looking forward to suggestions on did I make any mistakes in the implementation.
main.dart file
...ANSWER
Answered 2021-May-04 at 13:48Greetings from Syncfusion.
On analyzing the given codes, we can reproduce the reported UI lag in page transition. Syncfusion Flutter PdfViewer loads the PDF page's image which is rendered using native platform's renderer and this process takes some time to load a PDF document. Image loading is indicated using LinearProgressIndicator. To resolve the issue in page transition, we recommend adding Future.delayed before loading every pages. We have modified the code and shared for your reference. The Modified code can be downloaded from the following link. https://www.syncfusion.com/downloads/support/directtrac/general/ze/book496455946
Please let us know if you have any doubts.

I held off a long while thinking I would come across the answer, but I still haven't so I'm giving SO a shot
...ANSWER
Answered 2021-Apr-16 at 12:57Even though learning about mapped types is always a good plan, you don't actually need them here. By just creating a non-generic function that does a lookup in previewTypes, the correct result type can be inferred.
First, you can simplify the types a bit by deriving them from the previewTypes:

I have a PdfViewer dialog in my webapp created in React, it displays pdf-s using this package: https://github.com/wojtekmaj/react-pdf , it has a scale property to define the scale of the pdf viewer component as such:
...ANSWER
Answered 2021-Mar-08 at 21:48I haven't found such option in their github, so you would need to implement it yourself.
You will need:
- Two state values - one for target scale, and one for current scale.
- Knowledge of
setTimeout - A bit of arithmetic
Basic and very slow example:
QUESTION
In Firebase, I'm getting various crashes in my production app (uses Dexguard), while using Parcelable.
These crashes are now affecting almost 200 users and are grouped into 3 entries on Firebase.
In one entry, crashes are only on Samsung devices, in another, are only Xiaomi devices and in the other, are more brands but 81% are from HMD Global.
ALL these devices are running Android 10 so this might be a problem with this OS version. I can see that the crashes are contained to 5 or 6 custom objects. Other than that, some crashes are related to:
...ANSWER
Answered 2021-Jan-31 at 18:43This problem was reported a year ago for your first stack trace, the one referring to FragmentManagerState. It seems to be tied to an Android 10-specific bug.
For your InfoState crash, putting the object into the bundle as a byte[] should clear up the problem. That is not an option for you with FragmentManagerState, though, as that is being done deeper in the Jetpack.
You might want to confirm that you are on the latest androidx.fragment and androidx.activity libraries, in case they added a workaround. Otherwise, you might review the comments on that issue, as some developers reported some solutions, but they are rather specific and may or may not relate to your scenario.

QUESTION
I implemented a PDF Viewing widget in C++ using Qt, loosely based on https://doc.qt.io/qt-5/qtpdf-pdfviewer-example.html, using the pdfwidgets module. (For this question, we can assume that I copied the code in that link 1:1).
This works well so far.
But now the thing is, the PDF I want to display happens to be an animated PDF. Opened in a regular viewer like Acrobat, it will show a short sequence. That sequence is located on a single page, the frames are not different slides.
In the documentation of the QPdfDocument and the QPdfPageNavigation classes, I can't find any functionality that deals with animated pages. It would suffice if I had any way to set the current animation phase.
Is this possible at all? If so, how?
...ANSWER
Answered 2021-Feb-08 at 15:12It's not implemented at the moment. On Windows, you could use an ActiveQt widget to embed Acrobat Reader inside your application, if present. Otherwise you'd need to find a PDF rendering library - most likely a commercial one - that has such support.

This is the Image of my app enter image description here
I am stuck at loading fragment at correct tab position. Whenever i am running my app,the fragment in my first tab is displayed in all tabs of viewpager and also the first tab file is displayed again over the fragment.
This is my MainActivity.java
...ANSWER
Answered 2021-Feb-04 at 07:28You are attaching ViewPager and also DocumentFramgent both at same time, I assume mainContainer has DocumentFragment and Viewpager also has DocumentFragment, which is causing the issue
If you want only one fragment, then can remove 4th line in onCreate of MainActivity
