### *Example Input Text:*

You are tasked with analyzing a sudden shift in customer preferences in a tech market. There has been a noticeable decline in demand for physical devices, with customers increasingly interested in digital-only options. The challenge is to understand this shift, generate hypotheses for why it might be occurring, and explore potential strategies for adapting to this new trend.

---

### *Processed Output with System 1 and System 2 Thinking:*

The tech market is experiencing a shift in customer demand, moving away from physical devices toward digital-only options.

[sys1]
Customer demand has shifted from physical devices to digital-only options.
We need to understand why this change is happening and find strategies to address it.
Key factors may include cost, convenience, and technological trends.
[end sys1]

[sys2]
**2.1 Understand the Problem:**
The goal is to understand the underlying reasons for the shift in demand from physical devices to digital-only options, then develop a strategy to adapt.

*Reflection:* 
"I understand that preferences are changing, but what might be driving this? Is it primarily cost, or are there other factors such as convenience or sustainability?"

*Creative Perspective:* 
"Could there be a larger trend in digital minimalism or a preference for eco-friendly solutions that we’re missing? What unseen motivations might explain this shift?"

**2.2 Analyze the Information:**
There are multiple possible factors driving this shift, from economic influences to cultural shifts. It’s essential to isolate each factor and understand its impact.

*Reflection:* 
"Am I fully considering the various economic and social influences? Could there be a technological factor, like better internet speeds, that makes digital-only products more accessible?"

*Creative Perspective:* 
"Are there patterns or trends in other markets that could shed light on this shift? Could this be part of a larger trend toward virtual experiences?"

**2.3 Generate Hypotheses:**
1. Customers prefer digital options due to lower costs. (Confidence: 0.8, Creative: 0.4)
2. There’s a growing trend toward minimalism and reduced physical clutter. (Confidence: 0.7, Creative: 0.7)
3. Digital products offer greater flexibility and ease of use. (Confidence: 0.6, Creative: 0.6)
4. Environmental concerns are pushing consumers away from physical goods. (Confidence: 0.6, Creative: 0.8)
5. Advances in tech make digital-only options more functional. (Confidence: 0.8, Creative: 0.5)
6. Pandemic-era remote work increased demand for digital solutions. (Confidence: 0.7, Creative: 0.6)
7. Media coverage of the environmental impact of physical devices affects preferences. (Confidence: 0.5, Creative: 0.7)
8. There’s an increase in global digital literacy, expanding market access. (Confidence: 0.6, Creative: 0.6)
9. Customers view digital as more convenient and scalable for future needs. (Confidence: 0.7, Creative: 0.5)
10. Younger consumers prefer the aesthetics and convenience of digital products. (Confidence: 0.6, Creative: 0.6)

*Reflection:* 
"Have I considered all possible influences? Are there any surprising factors that could explain this shift?"

*Creative Perspective:* 
"Could specific social trends, like the rise of influencer culture or digital-first lifestyles, be influencing customer choices?"

**2.4 Anticipate Future Steps and Obstacles:**
*Objective:* Anticipate possible challenges, such as resistance from segments still preferring physical products.

*Reflection:* 
"What market obstacles might we face if we shift our focus to digital-only? Are there sub-segments that still prioritize physical products?"

*Creative Perspective:* 
"Could expanding digital options help us reach a more global audience? Are there emerging trends that we could leverage in our strategy?"

[end sys2]

[sys1]
To address this shift, consider a strategy that incorporates both digital-only offerings and educational campaigns about the benefits of digital solutions.
Use insights from customer feedback and current trends to guide product development.
Focus on flexibility and adaptation to cater to different customer segments.

Q:

Fastest Way To Display 100 or more images in Flutter

The purpose of this question is to find the best way to display a lot of images (20 or more) from the gallery. 
I need to display all the photos on the on the device. As you can see there could be a lot of images to be displayed, and when I try to display them all using different Image.file() widget, My phone (LG G2) gets slow and then the app completely crashes. 
I think the Problem Is that I am Loading a lot of 4K Images (More Than 100) on a 5 years old Device. The Images actually displayed on the Screen at the same time are actually around 15, but I need to have something like a gallery, so all the images in a GridView.
So, I don't think it's the best option, maybe there is a function to downscale the image to like 100x100 px. But looking online I couldn't find anything. So, Is there a better way?
I get all the Image Paths and their folder using a Platform Channel to Android. 
I get them all in a list like this:
[["Camera", "storage/emulated/0/downloads/1.png"], etc] 
This is The UI I got: (Sorry For the Awful design)

There Are three Main components on the Screen, The IconButton With The Two Arrows:
The DropDownMenu and The GridView.
The IconButton requeries all the paths from android. in the List as stated above.
The DropDown Menu has a function on onChanged which creates all the Cards in the List used by gridView.
This is The Funciton:
void _onChanged(String value) {
    setState(() {
      _currFolder = value;
      _photoCards = calculatePhotoCards();

    });
  }

And the calculatePhotoCards is this:
List<Widget> calculatePhotoCards() {
    List<Widget> list = new List();

    for (int v = 0; v < _foldersAndPaths.length; v++) {

      if (_foldersAndPaths[v][0] == _currFolder) {

        list.add(Card(
            color: Colors.white,
            shape: RoundedRectangleBorder(
                borderRadius: BorderRadius.all(Radius.circular(20.0))),
            child: Padding(
              padding: const EdgeInsets.all(8.0),
              child: new ClipRRect(
                borderRadius: new BorderRadius.circular(8.0),
                child: Image.file(
                  File(_foldersAndPaths[v][1]),
                  fit: BoxFit.cover,

              ),
            ),
          ),
        ));
      }
    }

    print(list);
    return list;
  }

Where _foldersAndPaths is the List containing all the paths which their respective folders (as stated above), while _currFolder is the Selected Folder in DropDownMenu.

A:

I decided to implement this to see if it was something to do with image sizing etc, as there have been a few questions about that in the past for remote images.
When I implemented it, I ran into the exact same problem as you. I thought that flutter did caching of images scaled to a reasonable size but that doesn't seem to be the case. It's actually loading up each image into memory, which is why you're getting a crash. It doesn't take that many images to run out of memory as by the time they're decoded into pixels they're pretty huge.
Here and here are bugs about this (I raised one myself) against flutter.
So unfortunately, I don't think there's a pure flutter way of doing this at the moment. There is a image package on pub that can scale down images but it does it directly in dart code so isn't all that performant.
Until those bugs have been fixed, you may have to look for an android-specific (and iOS-specific if you're interested in that) solution to this. That would entail using the android thumbnail creator to create a bitmap, then either saving that bitmap and passing it's URL back to flutter, or passing the bitmap's bytes directly.
Sorry I don't have a better answer than that!
