I had many issues reading
the Flutter documentation to get how to make a page transition; either I want it
to transit upwards, downwards, forwards, or backwards. However, although the
Flutter official site is well documented, you will not easily understand how to
easily make this.
It took me some time to understand how to make this, it was not that much line of code compare to what I saw of the official site that got me tired while going through it, I still went to YouTube and other sites to see if I can get what I want, but not really.
What I saw actually was what I was looking for but I wanted something that would be easier to follow and make other people understand.
Please if you still do not have any good knowledge of Flutter I will advise you going back to the basic until you are comfortable with what you are doing to move to the advance.
So I will not be saying much about this or explain much, but I will be dropping the code for you and please if you do not understand let me know and I will do my best to explain to you how it works.
The code will be shown below:
