Flutter Modal Bottom Sheet Tutorial

📗 Get the code from this tutorial 👇👇

Screen sizes are changing, they're getting ever bigger and almost without any bezels. While having a bigger screen is awesome, users often cannot reach to the top of the screen with only one hand.

For us, developers, this means putting more controls to the bottom of the screen. This is true for both the app bars and navigation drawers.

In this tutorial we're going to focus on the bottom navigation drawer and we're going to implement it as a modal bottom sheet. We're also going to make it look nice and material with rounded corners.

2 things:
1) showModalBottomSheet has a shape param which lets you specify the radius without having to replicate the overlay color manually.
2) No need to hardcode the height when you use Column since you can set mainAxisSize to min.


I'm currently in search of another question: How can you configure opening and closing animation?

I really appreciated that you planned ahead for your video. You pasted code snippets in rather than typing. The results were a much more effective video. Thank you.

how can i make it above bottom navigation bar as it appear to hide the bottom navigation bar

[viharcontractor]

Great tutorial! You could've used Colors.transperant on the outer container, leaves out the hassle of trying to figure out the background color imo.

Hey, you can use showModalBottomSheet -> backgroundcolor, if you would do this, didn't need container color, thanks for tutorial

[kbyo]

Is possible load the bottom sheet only every first time that you open the App??? If it is possible, how can it do it??? I'm sorry but I'm starting... 😅 Thanks!!!

Can you make one for ios 13 like one?, I found flutter_bottom_sheet but is not cupertino at all :(

[laujimmy]

Please help!!! how do you show a bottom sheet dialog with textField in iOS ?
I know that showModelBottomSheet is only used in material, and it takes care of the keyboard height.
However it won't show up if I used CupertinoApp, anything is helpful, appreciated.

[rahultirkey]

What emulator is that? Is that the emulator provide by android studio or anything else?

You should set the canvas colour to transparent rather than add another container to make the rounded corners show.

Hi, Reso Coder your videos are great.

I tried your video to use showModalBottomSheet but I'm getting this error.


═══════ Exception caught by gesture
The following assertion was thrown while handling a gesture:
No Scaffold widget found.

It would be great if you could reply.

@Reso Coder Hello man, a solution to the background is it
"void onButtonPressed() {
showModalBottomSheet(
Colors.transparent,
context: context,
builder: (context) {}"



thank you very much for this tutorial
