GradientContainer class

Gradient Container is a classic container rounded and filled with a gradient color. Depending on its params, user can change most of its UI. Params are defined as follows:

  • gradient is the main gradient used to fill the container
  • gradientOnBorders is a bool param to move the gradient on borders. If true it override the Container background and fill it with a Colors.transparent color.
  • color could be used to override the default color of the container. If specified it overrides the gradient in case of gradientOnBorders false, otherwise the background color
  • borderColor could be specified to override the borderColor. It overrides the gradient in case of gradientOnBorders true, otherwise it colors the Container borders
  • borderWidth the width of the Container borders
  • borderRadius the Radius of Container Borders
  • constraints helps the user to have a dynamical components that respects defined constraints
  • size helps the user to force the Container Size. If specified it overrides constraints
  • isExpanded will expand the container in horizontal
  • contentAlignment specifies the content Alignment of the container
  • padding defines the padding between the child/label and the container borders
  • label can be used in case you just want to show a string inside the container. If child is not specified and label is null, the label default value is set to Empty String
  • labelMaxLines in line with AutoSizeText library, you can specify how many lines the label can use before starting reducing its fontSize to adapt the label to the constraints or size
  • labelFontSize is the fontSize of label
  • labelColor is the color of label
  • child can be used to override the label text widget
