Basic examples

See the full example here. Most of the examples are in the rows_in_progress_bar_example folder.

Example numbers correspond to their numbers in the code. To quickly find examples in the repository, look in the code: 'EXAMPLE CODE'.

Colors

Example 01, 02, 03

Dart code 
// Example 1
SimpleCircularProgressBar(
    progressColors: const [Colors.cyan],
)

// Example 2
SimpleCircularProgressBar(
    progressColors: const [Colors.cyan, Colors.purple],
),

// Example 3
SimpleCircularProgressBar(
    progressColors: const [
        Colors.cyan,
        Colors.green,
        Colors.amberAccent,
        Colors.redAccent,
        Colors.purpleAccent
    ],
    backColor: Colors.blueGrey,
),

Start angle

Example 04, 05, 06

Dart code 
// Example 4
SimpleCircularProgressBar(
    startAngle: 45,
),

// Example 5
SimpleCircularProgressBar(
    startAngle: 90,
),

// Example 6
SimpleCircularProgressBar(
    startAngle: -180,
),
 

Thickness of the lines

Example 07, 08, 09

Dart code 
// Example 7
SimpleCircularProgressBar(
    size: 80,
    progressStrokeWidth: 25,
    backStrokeWidth: 25,
),

// Example 8
SimpleCircularProgressBar(
    progressStrokeWidth: 20,
    backStrokeWidth: 10,
),

// Example 9
SimpleCircularProgressBar(
    backStrokeWidth: 0,
),

Merge mode

Example 10, 11, 12

Dart code 
// Example 10
SimpleCircularProgressBar(
    progressColors: const [Colors.cyan],
    mergeMode: true,
),

// Example 11
SimpleCircularProgressBar(
    progressColors: const [Colors.cyan],
    fullProgressColor: Colors.deepOrangeAccent,
    mergeMode: true,
),

// Example 12
SimpleCircularProgressBar(
    progressColors: const [Colors.cyan, Colors.purpleAccent],
    mergeMode: true,
),

Animation time

Example 13, 14, 15

If you don't need animation, set animationDuration = 0.

Dart code 
// Example 13
SimpleCircularProgressBar(
    mergeMode: true,
    animationDuration: const Duration(milliseconds: 500),
),

// Example 14
SimpleCircularProgressBar(
    mergeMode: true,
    animationDuration: const Duration(seconds: 3),
),

// Example 15
SimpleCircularProgressBar(
    mergeMode: true,
    animationDuration: const Duration(minutes: 1),
),

Text

Example 16, 17, 18

Dart code 
// Example 16
SimpleCircularProgressBar(
    mergeMode: true,
    onGetText: (double value) {
        return Text('${value.toInt()}%');
    },
),

// Example 17
SimpleCircularProgressBar(
    valueNotifier: valueNotifier,
    mergeMode: true,
    onGetText: (double value) {
        return Text(
            '${value.toInt()}',
            style: const TextStyle(
                fontSize: 30,
                fontWeight: FontWeight.bold,
                color: Colors.white,
            ),
        );
    },
),

// Example 18
SimpleCircularProgressBar(
    valueNotifier: valueNotifier,
    mergeMode: true,
    onGetText: (double value) {
        TextStyle centerTextStyle = TextStyle(
            fontSize: 30,
            fontWeight: FontWeight.bold,
            color: Colors.greenAccent.withOpacity(value * 0.01),
        );

Value Notifier Example

Example value notifier

You can read about how ValueNotifier works here.

The source code of the example can be found here.

Parameters description

Parameter Default Description
size
double		 100 Widget size.
maxValue
double		 100 The maximum value of the progress bar. The values will vary from 0 to [maxValue].
startAngle
double		 0 The angle from which the countdown of progress begins.
progressStrokeWidth
double		 15 Thickness of the progress line.
backStrokeWidth
double		 15 Line thickness of the background circle. If you don't need a background circle, set this parameter to 0.
progressColors
List		 Progress bar can be either with or without a gradient. For a gradient, specify more than one color in the [progressColors] field and if a gradient is not needed specify only one color.
fullProgressColor
Color		 The color of the circle at 100% value. It only works when [mergeMode] equal to true.
backColor

animationDuration
int		 Duration(seconds: 6) Animation duration. If you don't need animation, set this parameter to zero Duration.
mergeMode
bool		 false When this mode is enabled the progress bar with a 100% value forms a full circle with [fullProgressColor]. If no [fullProgressColor] is specified, the last color from [progressColors] is taken.
valueNotifier
ValueNotifier		 The object designed to update the value of the progress bar. By default, creates a ValueNotifier with the maximum value.
onGetText
Text Function(double)		 Callback to generate a new Text widget located in the center of the progress bar. The callback input is the current value of the progress bar.
