Charts

FlutKit provides a collection of ready-made chart implementation examples intended as learning references. These chart screens demonstrate how to configure, style, and integrate charts within a real Flutter dashboard layout.

Important
These charts are not reusable widgets. Developers are expected to study, modify, and copy relevant code into their own projects as needed.

Available Chart Examples

FlutKit currently includes the following chart implementations:

• Line Chart
  Used for trend visualization over time.
• Column Chart
  Suitable for comparing values across categories.
• Spline Chart
  A smoothed variation of line charts for better visual flow.
• Area Chart
  Emphasizes magnitude by filling the area under the curve.
• Bar Chart
  Horizontal alternative to column charts.
• Bubble Chart
  Visualizes relationships using size, position, and color.
• Scatter Chart
  Displays correlation between two numerical values.
• Error Bar Chart
  Demonstrates uncertainty or variability in data.
• Step Line Chart
  Useful for showing discrete changes over time.
• Range Column Chart
  Represents value ranges instead of single points.
• Financial Chart
  Includes examples such as candlestick or OHLC charts.
• Histogram Chart
  Shows data distribution across value intervals.

Source Code Location

All chart examples can be found in the following directory:

lib/views/screens/chart

Each file typically demonstrates:

• Chart configuration and series setup
• Sample (mock) data modeling
• Axis customization
• Tooltips, legends, and interactions
• Theme and color integration with FlutKit

Recommended Files to Study

When learning from the chart examples, focus on:

• Chart screen widgets (entry point per chart type)
• Data model or mock data definitions
• Chart-specific configuration (series, axes, markers)
• Theme and color mapping logic

How to Use These Examples

1. Open the relevant chart screen file.
2. Study how data is structured and bound to the chart.
3. Copy only the required parts (series, data model, styling).
4. Adapt the code to your own business logic and state management.

These examples are intentionally explicit and non-abstracted to make the learning process clear and practical.

If you plan to customize charts extensively, we recommend reviewing the data model and lifecycle handling patterns used across FlutKit chart screens.
