First, let's change onPressedBehavior and add a button to the dialog builder. Well, sometimes we'd like to have a physical button like "Next tip" to navigate us to the next entry instead of just tapping at the screen. There isn't much to highlight multiple items, you just need to create multiple keys.ĭon't worry about the animations, they'll run smoothly between entries. Then we can adjust the builder to a currently selected item. So let's get down to work and start by creating a list that'll contain objects with text and alignment. ![]() Second of all, because the description doesn't match what's highlighted. Well, first of all, because we've set it to be in the middle of the screen and it's kind of in the middle of our highlight item. You could notice that I've hidden the description text in the previous example. The code below makes the highlight section smaller.īut if we want to make it even fancier, we can round the edges like that: Using different texts on different pages If we create a tutorial entry from RRect value, we can adjust the highlight section to whatever shape we want, we can make it smaller, bigger, round the edges, etc. We can easily adjust the highlighted item size. Well, if we pass the key, it'll highlight the whole area, but we probably would want something smaller that shows only the text part, but don't worry! You don't need to change your UI code. Let's add some more highlight items to our flutter tutorial and let's start with the large text in the middle of the screen. Which altogether gives such an effect: Changing the size of the highlight Tutorials are typically made to guide us through the part of the app that's not that obvious. Usually, in tutorials, we don't want to just highlight items. You can also adjust the final opacity after animation, by default it's set to 0.5. ![]() Then we just need to start the tutorial and pass TutorialEntry with a key. Let’s start with something simple such as, for example, the widget that selects fonts.įirst, we need to create a global key and assign it to the widget. Let's first decide on what elements we'd like to highlight. I have prepared an example app that doesn't have any functionality but the final effect is more eye-catching. In this article, I'm going to go through the flutter tutorial package and showcase the most interesting features. I could go in-depth on how to do that with flutter, but instead, I have created a package that does that for you. There are few unique takes on that, but I'll focus on the one that highlights certain parts of the screen. These days mobile apps tutorials are kinda frequent.
