The Flutter dating software
This new application is simple: you swipe directly to such and you can kept in order to dislike. As you can plainly see on screenshot more than, i’ve a red arc record towards name and you will an excellent stack from notes for several users more than it. On the other hand, underneath the cards are just like and dislike keys that people can also be have fun with in the place of swiping.
Beginning with a basic credit heap
- BackgroundCurveWidget – Here is the red-colored arch gradient widget regarding record

Since i’ve BackgoundCurveWidget , we’ll put it from inside the a heap widget along with the CardsStackWidget misstravel free trial one to we’re going to be undertaking moving forward:
Carrying out character notes
In order to go ahead in the future, we need to produce the reputation cards first one to CardStacksWidget might be holding. This new character cards, as the seen in the last screenshot, is sold with a vertical image and also the individuals name and you will distance.
This is why we shall implement the newest ProfileCard getting CardsStackWidget given that i have our design class able on reputation:
The newest password for ProfileCard is made up of a stack widget which has a photo. Which photo fulfills this new Bunch using Positioned.fill and one Positioned widget at the end, that’s a bin that have a circular edging and you may carrying label and you can point texts to the ProfileCard .
