Overview flutter linear gauge

Key Features

  • Orientation - The Linear Gauge supports both vertical and horizontal orientations, giving you flexibility in your layout design.
  • Axis - The axis serves as a scale where values are plotted. You can customize the axis by adjusting its thickness and edge styles, and even inverse the axis direction.
  • Labels and Ticks - Axis elements such as labels, major ticks, and minor ticks can be styled in various ways to match your application’s design.
  • Ranges - Ranges are visual elements that help users quickly visualize where specific values fall on the axis track. You can add multiple ranges with different styles to enhance data visualization.
  • Pointers - A pointer is used to indicate a specific value on an axis. The widget has three types of pointers: shape marker pointer, widget marker pointer, and bar pointer. All the pointers can be customized as needed and you can also add multiple pointers in the Linear Gauge.
  • Mirror Gauge - The Linear Gauge can be mirrored. When the isMirrored property is true, all the gauge elements will be rendered in mirror effect.
  • Animation - Add visually appealing animations to gauge elements when they load or when their values change.
  • Interaction - The shape and widget marker pointers in the Linear Gauge support interactive movement through swiping or drag gestures, allowing users to change values dynamically.
