QUESTION
So, I have this document that contains a list of image path that its file have been stored inside Firebase Storage. So my problem here is, how can I use future builder to load out all the images.
I have try to display out a single file with this method and its works but I just cant connect the way to display out all the file by using Future Builder.
...ANSWER
Answered 2022-Mar-22 at 15:59As suggested by @Frank van Puffelen,If you have an array of image paths, you'll want to loop over those and generate a separate FutureBuilder for each of them.
QUESTION
In Flutter, I can use Draggable to drag an object, say an image. Also, using InteractiveViewer, I can pinch-zoom the same image. Am able to do these actions separately with the individual widgets, but not able to figure out how to do both together -
- Load image
- Pinch-zoom out to shrink the image
- Drag the above image to another location in the screen
How can I achieve this in Flutter?
...ANSWER
Answered 2022-Feb-18 at 07:55If you just want to scale an image (zoom in/out), you don't have to use InteractiveViewer
. You can use GestureDetector
to do scaling, rotating, and moving, all at once.

QUESTION
Since I migrated my project to version 2.8 and with null-safety, I have had this error which I do not know how to solve it; below I put the video.
My red container measures 1700 x 1200, I sent that same measurement to CustomPainter, however it seems that when drawing, it takes the measurement of my phone because when I zoom it (that's why i use Interactive, to zoom it), it still has the same measurement (I do not know what it is).
...ANSWER
Answered 2022-Jan-19 at 15:59I have done this in past and I can suggest what I did at that time.
first I would use GestureDetector
rather than InterActiveViewer
. Use it's onPanUpdate
method to add offsets like this maybe,
QUESTION
I don't know if the title is worded correctly, but I will try my best to explain my problem. I now have a function that updates the current user's location, which works fine. The problem is that the painted pointer remains at that exact position because the decoration is painted once inside the widget and never changes.
I have looked at how google does it with the marker object, but that didn't seem to work for my app because I am not using a normal map.

QUESTION
I can use the Interactive Viewer to zoom the image inside the Container. However, it seems that the scale of the image is changing, not that the image is enlarged inside the container.
Do you know how to zoom the image without going out of the container's area?

ANSWER
Answered 2021-Dec-06 at 22:26Wrap your top layer (the picture frame) widget with an IgnorePointer
, it will ignore user gestures, so the bottom widget can properly receive those gestures.
For example:
QUESTION
I have a gesture detector and wrapped it around a interactive viewer. But when I do, panning and scaling no longer work on my InteractiveViewer. Or atleast it responds very poorly to input.
This is my GestureDetector
...ANSWER
Answered 2021-Oct-29 at 12:51You can use a Listener
if you just want to get notified when user starts and stops touching things under it. With GestureDetector
there is no way you can catch gestures and also send it to InteractiveViewer
being it's child. Here is an example:
QUESTION
InteractiveViewer(
constrained: false,
boundaryMargin: const EdgeInsets.all(20),
child: Container(
child: GraphView(
graph: graph,
algorithm:
BuchheimWalkerAlgorithm(builder, TreeEdgeRenderer(builder)),
paint: Paint()
..color = Colors.black
..strokeWidth = 1.5
..style = PaintingStyle.stroke,
builder: (Node node) {
var a = node.key?.value as int;
var nodeValue =
_nodeData.firstWhere((element) => element.id == a);
//print('node Value : $nodeValue');
var _eid = (nodeValue.id).toString();
var _id = (nodeValue.uid).toString();
var _name = (nodeValue.name).toString();
return Center(child: rectangleWidget(_id, _name, _eid));
},
),
),
),
...ANSWER
Answered 2021-Oct-05 at 15:05I'm just relaying what I found in an closed issue but sjimbonator says
if you set constrained to true on your InteractiveViewer and wrap its child with an OverflowBox with Alignment.center it will center the tree.
and they follow it up with this example:

QUESTION
I want to be able to generate a subview every time a function is called, and have the new subview stacked on top of the previous ones so that every subview can still be interacted with separately. I have tried the following:
...ANSWER
Answered 2021-Aug-10 at 23:12Right now, you're not actually adding the result of addView
to the view hierarchy at all. You'll want a way to add the view to a stored list (I used a @State
variable) and then display those, most likely with ForEach
.
