Limited Documentation

Availability of comprehensive documentation with Maplibre is always challenging and developers initially found it tough to get going.

The technology is relatively new and finding adequate resources was a hassle. Developers found it tough to understand the complex issues of the framework.

Customization and Styling

Customizing map’s appearance like changing colours and adding markers or roping in custom map layers was a loathsome ask. It required to have complete understanding of the Maplibre and flutter framework.

Dynamic Symbol Generation

Generating symbol on the map based on changing data or user point was a challenging part. It required

Symbol Styling

Applying custom styling to the dynamic symbols was yet another tough ask.

Each character had unique properties, such as size and icon, needed dynamic assignment based on the data. We ensured that the symbols were visually distinct and getting things properly styled was a challenge.

Large Set of Data

It was taking a while, to show up as loads of data was getting loaded from the database at one go.

Dynamic Tooltip

Due to the lack of documentation in the Maplibre library, it was already a Challenging task to add popup cards on the different locations inside the map. It went up by a notch when we had to dynamically adjust the position of each box by the pointer location.

Performance Optimization

Due to the large data structure, most of the data being an array, website's response time became prolonged.

Retrieving Data Country Code

High-resolution maps, large datasets, complex overlays, and performance can be a concern when dealing with many dynamic symbols on the map.

Rendering and updating many symbols in real time can lead to performance degradation, resulting in slow map interactions and decreased user experience.

Community Support

Although the official documentation may be limited, developers did leverage the power of online communities, such as forums, chat groups, and social media platforms, to seek help and share knowledge.

Performance Optimization Techniques

To address performance issues, we implement some optimization techniques, such as the asynchronous loading of map tiles.

Additionally, leveraging Flutter's built-in performance profiling tools can help identify bottlenecks and optimize code for smoother map rendering.

Customization Libraries and Plugins

Flutter has a vast ecosystem of libraries and plugins that can enhance customization options for Maplibre. We have used https://github.com/maplibre/flutter-maplibre-gl SDK to achieve the desired customization and styling of the maps. This package has extensive documentation and community support, easing the development process.

Data Management

To tackle the challenge of dynamic symbol generation, we have used a data management solution to handle the changing data.

This could involve leveraging a state management library like BLOC to store and update the symbol data. By keeping the data centralized and accessible, you can dynamically generate symbols on the map based on the latest data.

Large Set Of Data

As a large set of data was getting loaded from db in one shot, we had to cut short the long request and break it into chunks of calls; we called the primary data upfront and called the details part of each data when clicked on the details section which increased the flow speed significantly faster.

Dynamic Tooltip

We used a JS function that returns the exact positions of each element; with this, we were able to put the cards in particular pointers successfully.

Performance Optimization

We created an algorithm that shortens loop rotations and returns the data much faster, the user experience stays better.

Custom Symbol Styling

In Maplibre, symbols don't support flutter widgets. It supports only images or text.

To address the symbol styling challenge, you can convert the flutter widgets into images and then use the images for the symbols.

By implementing these solutions, we overcome the challenges associated with Maplibre Flutter and dynamic symbols, enabling you to effectively generate, style, and optimize the rendering of characters on the map.
